[RVT 2016] SetParameterByName

I am having problems with a script that used to work flawlessly now all of a sudden not writting values out to the parameter:

It seems to not like the multiplication part as if I replace those variables, r_dl_klf and r_ll_klf, with hard numbers it will set the Parameter properly

This is on Dynamo because it’s the only one I could get to install an add-in for Revit 2016.

think I found the problem looks like the WallType.ByName was added in a later release of Dynamo for this version it should just be type.GetParameterValueByName.
