Material Collection Error...Says "None" when it's named.

I’m making a material collection parameter and when i drag it into my material, it gives me a error whenever I try to hook it into anything. In the screenshot you can see my material Parameter collection clearly has been name under Parameter Name, but in the material editor is displaying as none. I followed the instructions in the documentation closely…and it seems pretty simple…but i can getting the error…anyone?


nevermind, just saw I have to name it in the dropdown. Duh:)
