Door family materials and finishes parameter asking for length

[bryanKK8LW]

I am attempting to add door material to my door schedule and for some reason it is asking for a formula as the parameter has been setup to length.  Is their a solution to this?

It was created incorrectly as a Length instead of a Material parameter.  Delete the parameter and recreate it, make sure to select the correct parameter type.
