Button creation

Button creation

Hello
I would like to create a switch button to change the value on bool tag. In function configuration the only parameter that can be used for this goal is "set the value" but during runtime operation when I press that button appears pop-up window. My question is, how to make the button set the value with out pop up window just by pressing it.
When I use "Intern-Driver for internal variables" I can configure the button like a switch. But when I use any other driver ( Beckhoff for example ) button became unpressable and can not be pressed..
With regards
