ToolBox Cutom Properties!

I followed Sal's tutorial on toolbox.  He has some great stuff in there.  but i added some cutom properties to toobox. when i export it out to excell, the properties i added don,t show up, like his "Vendor" property did. They do show up when i insert a toolbox part, and i can fill in the info,  but i want to fill out the properties in excell(way faster).  Can someone tell me what im doing wrong?  i followed sals tutorial step by step.

Thanks!
