Material constants in user-defined functions for material properties

Hello,
I am trying to create my own material property by adding an analytical function. This is a function of one input argument (frequency), but it contains several material constants.
I was hoping to use "local properties" table in the corresponding material settings to create my own local parameters. So that my function could be neatly written e.g. like
f=A*x
instead of
f=2.2454*x
And according to the "Materials Library User Guide":
"These local properties are useful for parameterizing functions that describe material properties if they contain inputs other than those that are model inputs"
However, it looks like the analytical function I am creating has no access to the "local properties". For instance, if I try to plot this function, Comsol gives me the error "Failed to evaluate variable: -Variable: A", even though A is defined as a local property.
What am I doing wrong?
regards,
Hello Andriy Gorbach
