Greetings-
I have a grid that my staff enters half the data (white half below). The right half below comes from a form to another grid and gets pulled in via a VLOOKUP. On the form, the person has to select the correct slot number and that corresponds with the slot number row on the grid below.
The question and issue I'm having is in the example below if the first person selects slot number one and enters the data the V look up supplies it to the right of the grid in the yellow section however, if someone else goes and tries to reserve slot number one they get a successful form submission, but they never get any type of follow up stating slot one has been filled.
Do I have any options or formulas that would follow up if someone requests a slot that has already been taken?
