In your second example, the variable n doesn't contain a number but 
the actual value of the current item in the list.

Try this:

on tryLoopFor
   put "a,b,c,d,e,f" into charList
   repeat for each item n in charList
     put n & return after newCharList
   end repeat
   delete char -1 of newCharList ## delete final return
   put newCharList && "for"
end tryLoopFor
