KGPanels script help

[Kendian]

I'm trying to make a kgpanel hide or show with OnCLick script, but having no luck. I THINK I understand the concept, with having 2 panels, one for button, and one the named,'fetched' panel, but it doesn't seem to be working...it will show up once (default state is hidden) but when clicked to hide again, it throws an error, about a nil variable. The sample script on KGPanels page USED to work (although it was made for 3 panels, not 2) but it no longer does. I could have sworn there was a forum post that just had one script in OnCLick, that accomplished what I'm trying to.

TL/DR: Trying to find a script for kgpanels that will hide/show panel based OnClick, with only 2 panels...a button panel, and the panel it fetches.
