How to change mask popup Type Options using callback code?

I have created a mask for my system that allows a user to select a specific value from a popup window (the parameter name of the value is TypeIn). I am then attempting to use this value to display a specific set of type options in another popup window in the same mask. I am trying to use the Callback section to enact these changes but I am unable to get the type options to change. The callback code I am using is:

P = Simulink.Mask.get('therm/TC');

RangeCtrl = P.Parameters(1);

if RangeCtrl == 1

RangePar = P.Parameters(2)

RangePar.TypeOptions = {'Option1' 'Option2'}

end

I am unsure how to correct this error and have not been able to find other answers or documentation on this specific problem.

I found the solution. It was returning an object (RangeCtrl) and not the desired value (TypeIn), therefore making my if statement useless.
