Button to make variable

[Louveduval]

Hello I'm sorry to bother you again 

I try to make a button to change a varible  and have a mesure with a calendar date or an exercise date 

So I made 

and I my mesure sum(
{<
[Filtre CA vente] = {"Oui"},
[Type date]={'BL vente','Facture vente'},
Date={">=$(=AddYears(Max(vDatedébutex),-1))<=$(=Date(AddYears(RangeMin(Today(),vDatefinex),-1)))"},
AnnéeMois=
>}
[Montant HT vente])

But When I push in the button the variable doesn't change 

Can you help me ?  

Best regard

Hello,

If you want to make this change, you need to have two buttons and three variables : 

1.  Three variables : the two first variables are the ones you want to switch according to your need. The third one will allow you to do this action
   

   //The action variable
   vSwitch = 1

2. Two buttons : add two buttons, choose the action "Définir la valeur de la variable". For the first one, choose 1 for value, and 2 for the second. 
   
   You can add a condition for background coloration
   

   IF(vSwitch=1,Green(), Blue()) // and 2 for the second button​

3. In your measure expression : now, you can create a variable whose the value change according to the activated button

That's the global idea of the process. Let us know if it was helpful.

Regards.
