Inventor 2011: linking to parameters calculated via a rule

Hello Community!
I've been trying what I had hoped was a simple and straightforward use of rules & parameters, but things don't quite seem to be acting as expected.
Scenario is as follows:
Base part is a Factory part (.ipt) which can have some features turned on or off. Within this part I created a rule which sets a user parameter (Total_Length) to one of two values based on whether the particular feature is Enabled or Disabled. Simple enough.
This works great, and depending on which Factory component I select in the Part, the parameter is set to the correct value.
I've set this parameter (Total_Length) to export within the part.
In an assembly where I use this Part, I'd like to see the Total_Length parameter update as I select particular Factory instances of the Part using table select (I actually also have a table in the assembly for including other parts including this one with the Total_Length parameter). I enabled import of this parameter in the Assembly, and I see it in the Parameter List.
However, when I select an instance of the base factory parts where the Total_Length parameter should be different, it's static, always the same. (seemingly the same as the last value it had when I saved the base part).
I'm able to pass other parameters up the food chain (both constant values, and those calculated using formulas) but all of those are static with respect to the part (eg, don't change based on which Factory instance is selected).
I'm figuring this is either a very simple "newbie" mistake, or something that is not quite fully supported in 2011. I'm kinda stuck with this version for now, but if others out there are willing to help me think this through, I'd be quite grateful!
