Okay, I think I see what is going on. Which button adds the new row - is that the Start button? It looks like you are adding a new row, but your screen is still attached to the first row, so when you do a set column values it’s going to change the values in the first row of the table, instead of the row you just added. Anyway, I think we maybe should take a step back, because I think you might be making this more complicated than it needs to be. Can you tell me a bit more about the purpose of this screen? What is it that you are timing, and do you need to keep a permanent record of the time each time you start and stop? Also, have you looked at the [Stopwatch](https://www.glideapps.com/docs/reference/app-components/stopwatch-component) component? ---

What I wanted to do is this 1-List tab will show all the students profile when clicked on a particular student name \> student profile will be shown ( this is done via list). This screen will have a button that will take the user to a new tab **Timer**. Clicking this tab will mean that the student is ready to start their lesson. Once the button is pressed, the record of student name will be written in **timer** table and user will be brought to **timer** tab 2- In this **Timer** tab. There are 3 buttons starttime/stoptime/reset buttons. Starttime is to start the timer, stop will stop the timer, and reset will clear the screen. Start and stop will input timestamp in the **timer** row. (here I select add row) The row of num 1 and the row of num 2 are not in the same row. I need it to be in the same row. Trying to record that this time record is for which student. If the row is empty I won’t be able to tell whose time is recorded in the table. (here I selected set column values) ☹ ---

Would you want to use the one that is already there, or create a new one? Should it be possible to “Go Back” and start the timer for a 2nd student before the first one finishes, or would you only ever time one at a time? ---

If you see the row 4 is when i press the button on num 1 row 123 is what ill get when i press the start in timer tab answering to the question every time we start and stop a timer it should display timestamp of start , stop and duration. also the name of the student it is ment for. everytime we start again it will start a new line. the record will be completed once the stop button is pressed, or every time the start button is pressed new line will be recorded recording the start time and stop time also with new row is not a problem in my case. the problem is how do i get the name of student recorded along with the record pls ignore the blue sketches ---

Please have a look at this, and let me know if it does what you are trying to do. > **[Student Timing](https://student-timing-g87i.glideapp.io)** It can be copied, so you can make your own copy and study it to see how it works. ---

Its almost there but its not there yet. In this scenario If Tamsin login and start timer for Alan, the record will show Alan as subject IF Tamsin login and start timer for Tamsin , the record will show Tamsin subject needed scenario if Tamsin login and start timer for Alan, a record with info of Tamsin as recorder and Alan as the subject will be shown In this case Tamsin is the teacher and Alan is the student I will have hidden the Tamsin in the list, but in record still won’t have the info such as Tamsin as recorder and Alan as subject ![student](https://us1.discourse-cdn.com/flex002/uploads/glideapps/original/3X/9/f/9f89cd9de7ba93356b4333bea182e9a26d3764b8.png) ---

Okay, I understand. I made some changes to it, please try now. > **[Student Timing](https://student-timing-g87i.glideapp.io)** Note that the Teacher name is only saved if the Teacher is signed-in, otherwise it will appear as “Unknown Teacher” ---

The Helper table is (as the name suggests) a “Helper”, or “Working” table. This is something that many of us use in these types of situations. Strictly speaking it isn’t required, but it does help to keep some of the app logic separated from the app data. It will only ever contain a single row, and you will notice that both the “Student” and “Start” columns are [User Specific.](https://www.glideapps.com/docs/reference/basic-columns/user-specific-columns) This will allow multiple teachers to use it at the same time for different students without getting in each others way. `sv/helper` is a special type of [Single Value](https://www.glideapps.com/docs/reference/computed-columns/single-value-column) column. If you look at the configuration you will see that it looks in the first row of the Helper table, and takes the whole row. ![Screen Shot 2022-08-21 at 5.30.20 PM](https://us1.discourse-cdn.com/flex002/uploads/glideapps/original/3X/c/8/c857e31e6b72ec87b601b628548f0824df540224.png) The purpose of this one is to allow us to set the StudentID in the Helper table when we select a Student from the list. You can see that if you look at the custom action that’s assigned to the Students list: ![Screen Shot 2022-08-21 at 5.30.51 PM](https://us1.discourse-cdn.com/flex002/uploads/glideapps/original/3X/2/1/21febf8ec28d8553147aa2e44d58bff16c4ec4f0.png) Notice that it does a Set Column Values using the sv/helper column, which means that we are setting values in the first row of the Helper table. We set the values of the two user specific columns. Student is set to the StudentID of the student we just selected, and the value in the Start column is cleared, so that it’s ready to start timing for this student. ---
