Copy all Writable Instance Parameter Values from one Family instance to another

I am trying to copy all writable Instance Parameters from one Family to another inside a project (RVT). I have found the following thread but the Graph images aren’t readable: Copy Instance Parameters Between Two Families

This was very close but I receive an error.
