next repeat problem

[Rich Lague]

Thanks Klaus (and Jan!),

Yes, adding the complete descriptor for i did allow my 'next repeat' to 
run. However, I'm still having problems getting rid of the extra lines 
in my global variable.
I have also been trying your suggestion of using 'repeat for each'.

I get an error when I try to 'apply' this script--

---------------------------------------------------------------
set the itemdel to tab
repeat for each line i in fld "daTable"
if i = empty then
delete line i of fld "daTable"
else
put item 1 of field "daTable"  & return after theList
end if
end repeat

--------------------------------------------------------------
The error I get is "Chunk: error in chunk expression" and it highlights 
the line "put item 1 of field "daTable"  & return after theList" -- 
this is a line of the script that worked before...
