Hello

I am working on a Visio panel with a few buttons, the idea is to create a quick monitoring feature controlling a SDI matrix, I am trying to make it so that when a button is clicked it will set what is connected to a certain destination to a monitor output.

I have the source value in a session variable, 125 in the example.

is there a way I access this session variable in the SET string of the button?

I have tried using var:varName in this field but I am unsure of the correct syntax.
