Cant place door or doorframe after changing mesh

Hi,
I followed the tutorial for “your first mod” and switched out the mesh for the metal door. I have figured out collision and texturing, but in trying to place the new doorframe from inventory, nothing happens on “use”.

Any suggestions on where to look?
Also, still looking for how to override the door animation.

Thanks in advance,

Thanks for those that looked. I found the answer in this post.
