retrieving data from a sub-stack?

[Rich Lague]

I'm trying to get information from one sub-stack from another. The  
script below is from the sub-stack "productEvals". I want it to  
retrieve data from either the stack "RFP Importer-rich" or "RFP  
Importer-clean". It should involve a lot of going back and forth  
between the "productEvals" stack and one of the "RFP Importer" stacks.  
I can get it to go to the "RFP Importer" stack but I don't think it is  
coming back to the "productEvals" stack. What is the best way to get  
this working?

Thanks!

   answer "Which topic list did you use?" with "Rich's topics" or "My  
own topics"
   if it is "Rich's topics" then
      go invisible stack "RFP Importer-rich"
   else
     go invisible stack "RFP Importer-clean"
   end if
   repeat for the number of cards
     if field "topic" is empty then
       go next card
     else
       put field "topic" into tTopicsfld
       put field "Number" into tNumber
       put field "feature" into tFeature
       repeat for each line thisLine in tTopicsfld
         go card thisLine of stack "productEvals"
         put tNumber && tFeature & return after field "fromRFP"
       end repeat
       end if
     end repeat
