Okay…

So firstly, if all you wanted was a real time calculator:

- Use a table as the source of your screen that has only one row.
- Add a RowID column to the table (this isn’t used for anything, it just ensures that the row isn’t empty)
- Add columns for each of your inputs. These columns MUST be [User Specific](https://www.glideapps.com/docs/reference/basic-columns/user-specific-columns)
- Add a math column to do your calculation
- On your screen, DON’T use any type of form component or container.
- Just add a regular container, and then add input fields for each of your input columns
- Add a regular text type component and point it at your math column
- What you should then find is that as you enter values into your input components, the result of your calculation should be displayed and updated immediately
- If your need to “Reset” the input values, add a button to the screen and configure the associated action to do “Set Column Values”, clearing the value in each of your input columns

Next, if you need a permanent record of each calculation in a new row in a table:

- For this, you can use a regular form
- You will need a table to accept the form entries, and your form should be configured to write to this table
- Important thing to note here is that you will not see the result of the calculation in real time. This is because nothing is actually written to the table until _after_ the form is submitted (but see below)
- If you need to capture things such as which user submitted the form and when, you can use [Special](https://www.glideapps.com/docs/reference/values/current-date-time) [Values](https://www.glideapps.com/docs/reference/values/users-email-address) in your form

If you actually need both of the above - that is, save each calculation _and_ see the results in real time before form submission - that is possible by using a [Custom Form](https://community.glideapps.com/t/how-do-i-create-a-custom-form/25014).
