Activate Group by variable

I have a text variable "TXT" set to "" (empty)

and few groups Group A, Group B, Group C

and few instances of same sprites with different variables.

My setup is quite simple:

Mouse: Cursor is over sprites -> Set TXT to "sprite.variable"

Mouse: On click on sprite     -> Set group "TXT" Activated

everythings pretty but I can't find the way to pars text variable TXT value to the "set group active" expression.

strange but setting it like """" & TXT & """" returns "TXT", but don't works with group :)

It works fine here. Maybe provide a .capx?

Ahh, I'm sorry. My fault, It is working. Found an expression disabling that group constantly in my events...
