How can i translate this expression to APPSheet code? thks

[J_jvs]

If cell A1 is equal to cell B1 then it is OK,
but if cell A1 is not equal to cell B2 then it shows a message saying “incorrect number, please try again”.

I think you will have to explain more about you column and app layout. I doubt your app column names are A1 and B1. Those are cells in your sheet, but have header/columns names in Appsheet

You can read the following to get more information:

In AppSheet-speak, A1 and B1 are both column values (from columns A and B) in the same row (row 1). An expression to test inequality of two column values of the same row would be ([A] <> [B]), assuming the AppSheet table column names were also A and B.

You really should read some documentation:

help.appsheet.com

Thanks Steve and MIke for your quick response.
I’m reading the document.

This is the Spreadsheet formule that i want to convert to appsheet code:
=H2=F2

[Steve]

What are the names of the columns in you app that correspond to columns H and F in your spreadsheet? If you know that, we’ve already given you the answer.
