Colunms not showing

[Sebastian_Avila]

Hi everyone, i have this form view app and the users capture a number, after that the calculates the tax for that price and the grand total, all through a spreadsheet formula. it was working fine and recently y realized that appsheet wasn´t showing the columns with the spreadsheet anymore. What can i do to show the columns again?
Thank you.

A column that is empty and not editable will automatically hide itself - because there’s nothing to show; but if it’s editable then the empty space is shown so people can edit the field.
