Unit Types Mismatch

[cadman777]

During CC Customizations, I ran into this error:

"Unit Types Mismatch" (see attached screen shot).

Does anybody know what causes it?

I made my own "MAS" parameter and used "lbmass/ft" units.

I did that in the ipt's User Parameter and in the CC Family Table > Column Properties > Units field.

I want the CC FT to push the value into the ipt User Parameter.

But in the CC Family Properties > Parameters Mapping, The Category Parameters' "Mass per length unit" field rejects my attempt to connect the Table Columns value (which is "MAS"). The program gives the above error.

I'd like to know how to fix this problem, as it is inconsistent w/the program's function on all my other FT/ipt User Parameter values.

Please advise. Thanx!
