Laura, it sould like a valiant effort so far.
Have you burped the system?
There could be a big air bubble in the heater core that will not allow any anti-freeze to flow through.
Never try to pick a car up over the shoulder and attempt to burp it. :) Instead take a 10MM socket on a long extension ratchet and do this: Open the hood and stand right in the middle in front of the engine. Look in and downward to about the first arm of the injector plenum. That's the big, flat black piece of plastic on the engine with six arms sticking out to the left and right side on top of your engine. Look carefully downward and look for a little nipple sticking out just to the right of center on the top-front on that area. As a guide, follow the top hose from the radiator to the aluminum manifold. Look carefully and you can see it looking back at you. Stick the 10MM socket onto it and turn it COUNTER CLOCKWISE to break it loose. Once loose, either air, or anti-freeze or air AND anti-freeze will come out. To avoid a mess plug in a 1/4" clear hose to it and stick the hose into a bucket. Start the car and watch the air and liquid come out. When it runs clear without any air, give the hose a light twist CLOCKWISE to close it up. Tighten with a wrench. In this process make sure you don't get burned from the anti-freeze or make a big mess on the driveway. Dispose of the used Anti-Freeze properly. and GO!
