Getting the Filter Active

I've added the necessary features and filters to a category of products, but I'm not able to get the filter to show up on the category page.

I tried Blocks>Categories and added a filter block to the grid where the main content resides. Then I clicked on the gear wheel of the newly added filter block and added the category I wanted filtered, but no luck.

Any idea where I might be going wrong?

Never mind… by some miracle I got it working!
