Dear Community,

I am trying to come up with a simple script button that clears all the quantity to zero on my item sublist.
I've already have a custom button on my item sublist.

I've tried using   selectLineItem, setLineItemValue through a loop  to change all the qty on my list.
...for 13+ item lines on my item sublist.

it works, but it takes about 8 seconds (freezing up)...way too slow.
is there a better/faster way to clear all the quantity to zero?  i don't want to remove the lines.  i just want to set it to X qty for all items
