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”.
