Add the value to the previous one when editing a number value

[eric_niedergang]

Hello,
I'd like to do something quite simple but not obvious.
When I modify a numeric value, I'd like the new value I enter to be added to the old one.

Do you have any ideas on how to do this?

Thanks

Do you want to add that new number to the same column or to another one? And do you want to do this in the same record?

Hi, Yes and yes
I want to add the new number to the same column and the same record
Every time I enter a value, I want it to be added to the previous one.

Maybe, i have to use a _INPUT ?

[eric_niedergang]

[myrecord] = [_input].[data]+[myrecord] ?
I need to test this. It will open a popup window asking for the [_input].[data] value but It will be a nice use of an [_input] value

You can do this with an action of type Data: set the values of some columns in this row.

Yes, I will do this !

Thanks
