Tradeskill Window Crash

[Arremis]

Here is the basic start of my tradeskill window mod, but it keeps crashing when I press the create button. Basically we have style changes, and a few things stripped out (as I usually do). Can someone tell me what's causing this mod to crash? XML was included, but removed due to problem solved

Thanks

EDIT: Ok, found the problem. Apparently, deleting the Grouper pages on the create screen caused the crash problem. To correct this, I simply moved them off the viewable part of the screen. Now everything is hunky-dory
