Hey, i have a number entry with max length of 14 characters, and every time my user put more than that it keeps working! But, if it puts more than 14 it gets a wrong response of the app. So i want to block it from receiving a response from the application if it puts more than 14 characters. Can i do that? ---

Odds are youll need to use a custom form vs native form as there currently is no way to set conditions on when the form can be submitted outside of making certain components required. Using a custom form, youd have to find a way to count the # of chars entered into your text entry and show a submit button if 14 or less. ---

Hi Joanna, As answered in your other post, yes you can do it by using the “text length” column if it’s a text entry or an If then else columns if its a number, and check it’s more than 14 characters. If condition is not matched, in your button, add a notifications saying it’s more than 14 characters, otherwise, do the actions. > Yes, max and min length for text entry only work in forms. > You could count the length of the text entry using a “text lengh” column. > Then on your button action, you set this logic: > IF, the data entered by user \> than your limit of character THEN show notifications “max characters X”.

Hey Lucas! So, I am trying to do that, but i cannot find my “text length” column on the options of my column sources. I [recorded a video to show you](https://www.loom.com/share/f46fcf6dd2c34379aa851b7dc1648d17), can you see what i am doing wrong? And, after doing that, i need to send the information inputed by the user to the other column “CNPJ/search” so all the logic works, i need to use the “Set Column” action? I dont know if it will work, because my “cnpj/search” is user specific, and i saw that “Text length” cannot be user specific… ---

> [@Joanna\_Delg](#): > > i cannot find my “text length” column on the options of my column sources You are trying to set the source of your entry component to a computed column. You can’t write values to a computed column as they don’t store values. They only compute them. > [@Joanna\_Delg](#): > > And, after doing that, i need to send the information inputed by the user to the other column “CNPJ/search” You should be writing to the search column. The purpose of the Text Length column is to then compute the length of the value in the search column. ---

As @Jeff_Hager said, you would need to have at least 2 columns, one containing the text and the other calculating the number of characters in the text. ![Capture d’écran 2023-04-24 à 16.01.39](https://us1.discourse-cdn.com/flex002/uploads/glideapps/original/3X/3/7/37c58958989ed927239b84ef46d7095749fd553e.png) ![Capture d’écran 2023-04-24 à 16.01.45](https://us1.discourse-cdn.com/flex002/uploads/glideapps/original/3X/7/c/7c00ec4caea0c08aa1526f0f2e4898f518eec1c6.png) ![Capture d’écran 2023-04-24 à 16.01.49](https://us1.discourse-cdn.com/flex002/uploads/glideapps/original/3X/b/2/b233a5fcb093b06eba9c3e0d1bd7a3931bde6074.png) Then if true allow your user to go on to the next step in your app. ---

They only compute them. hey!!! i didt it, thank you for your help! I created a relation between my “search column” and the “text lenght” column, than i created between the “text length” column and the response for the user.
