I wouldn't use "it" for this... there's a special global property called
"the dialogData" that I use and it is flawless. Your modal stack's OK button
should be:

on mouseUp
  global recentvar
  set the dialogData to cd fld "response"
  put cd fld "response" into recentvar
  close stack "dialog"
end mouseUp

and your mainstack should say:

  modal "dialog"
  answer the dialogData
  if the dialogData contains "cancel" then ...

BTW: A couple of suggestions:

1) Make sure you put quotes around all your object names (i.e. 'cd fld
"response"', not 'cd fld response')

2) I probably wouldn't name a stack with a common name like "dialog" - it
may become a reserved word some day.

3) Rather than 'close stack "dialog"' you can just say 'close this stack',
since it is apparently being executed in the stack "dialog".

4) You might want to use "hungarian notation" with your global variables,
prefacing them with "g", like "gRecentVar". Many of us do this - the skinny
