[Scripting Question] [19.1]Revisiting an Unsolved Question

[Junkyard Guard]

Hey, guys.
Still just trying to find an answer to this problem I had back in April. Any thoughts?

Hey guys, I have a question about an item I put into the game. It's a Key Item that calls a Common Event. Here is the script:

ItemHandlers::UseInField.add(:SANITYCHECKER,proc{|item|
   pbCommonEvent(7)
})

The item works and calls the Common Event just fine, but when the Common Event ends, it says "Can't use that here."
What do I need to do to fix that? I tried Googling and looking through the scripts but I'm not good with RMXP Scripts. I'm using Essentials v19.1.

EDIT: I found that if I Register the item for quick use and use it in the field, it uses it just fine without saying "Can't use that here." It only says "Can't use that here." when I use it in the menu.

You need to return a value from the proc.
next 0 means it wasn't used.
next 1 means it was used, but this item isn't used up.
next 2 means it was used, and the item was used up too.

Good Lord, I feel dumb. I couldn't find this anywhere. Thank you so much for your help! It works perfectly.
