Can't use preexisting parameter table and search parameters simultaneously

[ryanrbart]

The code doesn't allow both a preexisting parameter table to be used in addition to searching other parameters. This can come up in multi-step calibrations. In my case, I calibrated subsurface parameters and identified the top parameter set. I wanted to bring this parameter set in from a preexisting table and further calibrate fire effect parameters.

A solution will allow both methods to be used but will require some error checking in case both methods refer to the same parameter.
