goofy question about "repeat for each"

[jbv at souslelogo.com]

Hi again,

I finally solved the problem by modifying the loop
as follows :
     repeat for each line j in cc
       get item 1 of j
       add 1 to it
       put return & it & "," & item 2 of j after var2
     end repeat

But I still don't understand why the previous version
led to unexpected values...
