Need to use Quote "Grand Total" to populate Potential "Amount"

Hello team Zoho,

We would like to use the Quote "Grand Total" to populate Potential "Amount". I've found this related topic, but since I'm a novice in Deluge script and the script in the link attached is not working for us. I was wondering if the team of Zoho could help us out please (we use Zoho enterprise) ?!.

Many thanks in advance !.
