[RESOLVED][RPG Maker 2003]Mother 3 Styled Menu System Help

So, this morning, I was working on a Mother 3 Styled Menu. All was going well until I tested it once, and the cursor wouldn't move down. Turns out that it isn't detecting the Key Processing...at all. I don't know what went wrong though, may someone please help me? 

Here's a project with the required pictures and events: [removed]
(Warning, you need WinRAR to unzip)

I wanted to have:
-Separate inventories for each character
-Have a limited number of items for each character
-Be able to use the items (I can do that myself)

I recommend reading Kazesui's tutorials, specially pointers and then the custom item menu with dynamic sorting for any ideas and learning~ :3

Thanks, but no thanks. Not exactly what I'm looking for.
The way I'm doing it doesn't allow for stacking, which is exactly what I want.

He teaches about this and you didn't bother to check? :|
You didn't have to follow the entire tutorial or whatsoever.

Excuse my ignorance. 
Anyways, it works! 
Thanks for pointing me to that!
