I have the 9v terminal connected to the left leg of the FSR.
The 9V terminal of what?
the right leg is connected to a 10 kOhm resistor, which is connected to ground.
Why do you have another resistor? Use a meter to measure the resistance across the outside legs. Measure the resistance between one outside leg and the middle leg as you apply pressure. The outside resistance should not change. The middle to outside resistance should.
the right leg is also connected to analog ).
The FSR should be like a potentiometer. One outside leg is connected to a voltage source. The other is connected to ground. The middle pin is connected to the analog pin.
