CraigFL - That was my first thought as well. I have never seen multiple tops on one switch but that doesn't mean it couldn't be that way. It could also be two circuits (also not common). could also be a split circuit with a shared nutral. (not common).
So, to the OP - Look for a switch that you forgot you had and switch it back on, also check for a tripped breaker. If you find neither then switch your breakers off then on. If this doesn't solve your issue then it might be time to call an electrician.
