so... I have this programming project due , and I just can't seem to fix this bug.
--this is the script I'm using:

--- sorry, it's really long...
so, I'm having trouble with the offestCurve part (>offsetCurve -d $startOffset -n ($curveSelected + "guide")
. It keep coming up with an error " line 53: Too many arguments. Expected 1, found 0."
anybody know what I can do to fix it?
