Custom Property in a Design Table

Hello!

I'm new to working with Design Tables, and I have searched for answers to this, (and it has been asked... and answered...) I am on SW2014, and I'm trying to use a Design Table to drive a Pin Diameter and Length. This is no issue, works fine - however, I want to be able to pull that diameter and length into a part number to link to a BoM, so I wanted to use a Custom Property to drive this. However, I cannot get the Design Table to pull information from the Custom Property Tab! I have no idea what I'm doing wrong, I have read many threads where this seems to be no issue..

My Custom Property is "PinSize" right now, it just says "Test"
My Design Table has \$PRP@PinSize as a header... It just stays blank, no matter what I do. Am I missing something obvious? Feels like I'm going insane, I've included a picture of my Custom Property Page, as well as the Design Table.

I appreciate any input!

Thanks!
