Live Load Reduction...not reducing?

Dear Potential Helpers,
This is my first time using ETABS (other than the tutorial). Right now I am attempting to make sure that the gravity loads are getting to the columns. My dead load and unreduced live load seem to be accurate. However, my live load does not seem to be reducing. I am hoping my problem is simple (maybe I am just not looking in th right place). Here are a few details about my model:

- The structure is concrete and my slab is defined as a membrane. (well, where I am checking columns it is a membrane, it is defined as a shell elsewhere)
- The live load in which i wish to take a reduction is called REDLIVE and I defined it as load type REDUCE LIVE.
- Under options>preferences>live load reduction, I have selected influence area ASCE7-95.
- I am viewing the results by selecting a single column, running an analysis, and going to display>show tables, then selecting the appropriate loads and checking Table: Column Forces under Frame Output.
- I am running ETABS Plus V9.1.5

Any help you could offer would be greatly appreciated.

I was looking in the wrong place....apparently LLR isn't reflected in frame forces until after a design is run.

Thanks anyway, ~Nick
