When you replace item 4 of tStr with empty, you don't delete the item itself, you just make the item empty:
put "a/b/c/d/e/f" into k set itemdel to "/" put "" into item 4 of k put k -> a/b/c//e/f What you need to do is delete the item itself: put "a/b/c/d/e/f" into k set itemdel to "/" delete item 4 of k -- note the change put k -> a/b/c/e/f -- Peter Peter M.
