Automation newbie

Hello @ll,

I’m not a programmer and I’m a bit lost creating my first script. I would appreciate any tips or help:

I have a table for product stock, with several fields but quantity is the most important.

In another table, there is a link to this first table item’s name and I created a form to record in/out’s.

How would be the script so when you fill the form with a +/- quantity it’s add/susbtracted to the first table quantity field?

Thank you so much,
