Automatic counter for a row number

Good morning all !

I find myself with a problem: I would like to put an automatic number for each measurement in the “Selection ID” column.

For example, I would like for the next measurement the number “3” to appear in the “Selection ID” column.

Could you help me on this?

Thank you in advance.

Hi @Marco1212

You may want to use this expression:

In your case : COUNT([Numéro de mesure]) (or any other column, actually)

Be aware that row number is not a stable key-column, you may want to change it :slight_smile:

EDIT : this formula is to write in the Initial Value expression
