Family parameter glitch?

[revitworkbench]

Hi, I am trying to add a cuttsheet to my families. The families have several types. I wrote a shared parameter called "cutsheets" and added it to the family. Then I copy the directory that I want into here. The problem is that some, not all, of the types give the error message "This field cannot be blank. Enter text to continue." Followed by the error "Failed to apply family parameters" But it doesnt tell me any more information as to how or why, but Im like, I JUST added you to the previous type without a problem. Does anybody know what this problem is, and how to fix it? Thanks!

The warnings may not be related to the newly-created parameter (I'm assuming it's a URL Type parameter, and that can be blank). In your Family, is there a Parameter that is driving Model Text, by chance? If so, check through the Types and see if there is a blank entry causing this error.

Yes, and yes! I dont know how you knew to check that, but that was pretty amazing!
