I want to display a pop up at the opening of a query.
In this pop up user can choose a number N (a variable) : it's a number of days.
I want to use this number N chosen by user in another variable X which is in a selection S. I would fill this variable X by formula : Actual Date - N.
But i don't know how to do.
User must choose a number of days which will be used in a variable in a selection !
I hope you could help me.
