[Help] Making a custom usable item

I made an item called "Whetstone" which was made clickable. I also made a trigger that reads when it is being used, but problem is, whenever I click it, it doesnt do anything. I have another item called "Pet Summon Bag" which works when I click on it, just not sure why the Whetstone doesnt.

Make sure the item is perishable (if you want) and clickable (obviously). If not these problems then I think you actually have to add a SKILL that does something (a dummy or whatever you want) for it to actually trigger.

I made it perishable and clickable long ago. Problem is, I had it based off of the bag I used to summon the pet. So, I made a trigger that was basically very very similar to the first but it does not work for some reason, as though it doesnt read it.

EDIT: giving it the dummy ability "WhetstoneRepair" did the job. Thanks. I'll edit/post again if theres a problem.

EDIT2: Tested the repair item, and it worked flawlessly. Thanks alot. I never good with items/abilities.
