Controlling linear actuator with relay and Arduino

Hi everyone,

I'm relatively new to the electronics/ programming thing and I am working on a project with the Arduino Uno and the Evil Mad Scientist Simple Relay Shield. I have everything setup and connected and am just (for now) running the simple Blink program (but with longer delays). When I run the program, the LED on the shield blinks (like its supposed to), but the motor won't switch directions. It will switch when I have it connected to a regular manual SPDT switch though and have moved the wires accordingly. Also, it worked once or twice in the beginning, but now even when I change the "digitalWrite(RELAYs2, LOW)" to HIGH, it wont switch. I can't figure out what is going on.

Give us the code you are using. Also a drawing of the wiring.
