Wonderware toggle window button.

I want to make a button that opens a popup window when pushed, and closes that same window when pushed again. I can't seem to figure out how to do this. I think I have to do some kind of scripting, but I can't figure out how to open a window through the scripting routine.

Make it to where each time the button is pressed it toggles a memory bit to 0 or 1. Based on if the bit is 1 or 0 the window opens or closes.

On click if x=0 then x=x+1, if x=1 then x=x-1

or you could maybe have two buttons overlayed over each other and just control their visibility.

You can use a memory discrete tag that will monitor the state of the window, open or close. Then use the Show and/or Hide Window script in Action Script
