Beginners Game

Hello Guys,

Im working on a small vb game, the game is basically pushing boxes.
Everthing was going fine, until suddenly, the game is no longer doing what i wrote in the source code, i mean the source code is there , it just looks like its not being executed.

Here is the Source Code, i hope you guys can help me find this wierd error.
Timer1 set to true and the interval is 1
Timer2 set to true and the interval is 10
