Your problem is an extra "char" in there
>put char (theLast - 3) to char (theLast) of line 1 of field "result"
should be simply
>put char (theLast - 3) to (theLast) of line 1 of field "result"
with extra parenthesis if needed.

But the *solution* is what Richard suggested, i.e. use negative indices; 
except that "theLast-3" should be "-4", so
>put char  (-4 to -1) of line 1 of field "result"
