This is the crash report I am getting when I try to open my gui in-game.

The gui does display for a moment, albeit improperly, before crashing.

I followed the steps in this guide to create my gui.there were only a couple minor changes to function calls to match my forge version.

 

you can look at my code here.

Thanks, that fixed it!
