Modal dialogue "it"

[Andrew]

Hi, I have a strange problem.
I'm doing a very simple procedure  where my main stack calls a substack 
as modal.  Then, when you push "OK" in the substack, the substack 
closes and the contents of its field "response" is put into it.
Then, after the modal stack is closed, more code is supposed to run, 
but it just stops there, and it seems as though "it" was erased.
My mainstack says this:
on keydown whichkey
   put whichkey into field "response" of stack "dialog"
   modal "dialog"
   answer it
   if not it contains "cancel" then send continueStuff to this card
end keydown

I put "answer it" there just as a test (so that Rev would show me what 
was put into "it" after the modal dialog stack closes), and it just 
answers with a blank window.

The "OK" btn of the modal stack says this:
on mouseUp
   global recentvar
   put cd fld response into it
   put it into recentvar
   close stack "dialog"
end mouseUp

the global recentvar is there because later on, in continueStuff I need 
to access this value.

Thanks for any assistance!
