So I am trying to repurpose this script to pause a TS that must be run from the user's desktop while logged in. Everything works fine, I was able to change the text around to be informative to the user as needed and when they click OK or close the windows the TS progresses. What I was trying to do was instead of an indefinite pause, to use the timer option of msgbox. So basically I want the window to pop up and wait for whatever time I decided upon and then close and continue when the timer runs out. Can you assist in this if possible? I've researched some other TS pause options but this one works great and I just hoped to be able to modify it slightly for my use case.
