Add Quantity to Same Fields in Found Set
We would like to "+1" to the "Amount in Stock" amount in a found set.
We've set a variable so far, but want to, with the click of a button: find whichever category we need at that time, add 1 to the current amount for all the "Amount in Stock" for the current found set. There will be multiple categories by the time we are fully set up.
Screen shot attached. Thank you!
