1997 Blazer, How to remove grille

I need to know how to remove the grille. I opened the hood, and found 4 screws across the top, which I took off. but, it still seems stuck on there. Any help? PICTURES WOULD BE NICE!!

There should be two more screws on the front of the grill, one above the Chevy symbol and one below.

Also, there are probably 4 snap fittings that grip the tabs of the lower part of the grill and slip into slots of the metal just above the bumper.
