[Javier_Bruna]

Hi! I´m using the expresion: [_THISROW_BEFORE].[ubicación] to get de previous value of the colum “Ubicación” before de row was updated. Problem is the App displays de new value instead.
¿What am i doing wrong?

Hi @Javier_Bruna

Welcome to the community !

According to this article:

help.appsheet.com

Before and After Values

You can see the value of a column both Before and After it was updated.

We can read that:

The Before value is captured just before a record is updated. It contains the field values obtained from the worksheet or database record just before the update is applied.

This makes me think, regarding your question, that you expect at all time being able to see what was the previous value of your column.
I’m afraid the [_THISROW_BEFORE] won’t allow you to do so.

You may prefer instead using another column, that will store the “before values” along with the update action you are performing.
