[SOLVED] MouseClicked event not registering on a certain button

I’m really stuck on this stupid bug. I’ve tried absolutely everything to fix it. I made my own dialog box with 3 buttons and some text. It lets you choose a size for my game’s layout. The two buttons that let you change the size work perfectly, but the “ok” button doesn’t even register.

This is the dialog box

Here’s the code:
