I have a standard single pole single throw switch and I am installing an occupancy sensor. The existing switch only uses black wires on the switch, one on top one on bottom and the ground. The occupancy switch has one green for ground, one Red for Load and one black for line. Do I just put one black on RED one black on Black and green to ground?

According to the documentation for the switch you're using, a grounded (neutral) conductor is not required. The wiring diagram for your device looks like this
If your device isn't working, it's possible that you've reversed the wires. Make sure the black wire from the switch is connected to the line wire, and the red wire is connected to the load wire.
If the switch still does not function, verify that the grounding conductor is solidly connected, and that the ground is good.
If the switch still does not function, the device may be defective and need to be replaced.

You will need to determine which of the black wires on the original switch is the always hot feed. A voltage meter would be very helpful in determining this. Once you establish this, hook that black wire to the black,line, wire on your new switch. Hook the other black wire to the red, load, wire from your new switch and then hook up the ground wire to the metal box or to the bare copper wire.
