Window switching

[William Conable]

Here's my procedure:

global WasWindow
WasWindow= info("WindowName")
SuperAlert "[some text]", {title="Last Chance to back out!" 
buttons="I'm sure:100;I want to go back:120"}
If  info("DialogTrigger") = "I want to go back"
     SuperAlert "[some text]",{buttons="OK:60" title="No problem."}
     stop
endif
If info("DialogTrigger")="I'm sure"
     ServerUpdate "off"
     GoSheet; I had to do this because if the data sheet wasn't open it 
wouldn't do the fill
     Field «Letters going out»
     FormulaFill («Letters going out»+datepattern(today(),"mm/dd/yy")+" 
"+«Letter type»+"|")
     OpenForm WasWindow;*****
     WasWindow=""
     ServerUpdate "on"
     Synchronize
     SuperAlert "I've recorded that you sent this set of letters. Now go 
ahead and print the envelopes.",{title="Next Step" buttons="OK"}
endif

**** here's my problem. At this point the program stops and tells me 
there's no such form in the DB: but there is. (If I use Window 
WasWindow, it tells me there's no such window.) When I debug, the 
variable is correctly assigned. When I check in the Variables Wizard, 
the variable WasWindow has the value of the window I want to go back 
to. But somehow the program isn't getting it.

What don't I get? It seems to me I've done this before successfully. Of 
course if I could avoid all that window-switching it would be great 
too...

Thanks,
