Narrative:

We were cleared for takeoff and got the configuration warning at about 20 KTS. We rejected the takeoff and cleared the runway. We recycled the flaps and the flap indicator hung up at flaps 1 degree with the flap lever in the 5 degree detent. We contacted maintenance control who had us recycle the flap indicator circuit breakers and the flap lever. The flap indicator still hung at 1 degree while flap lever was at 5 degrees; [so we] went back to the gate. Maintenance came on and after recycling various flap circuit breakers and flap switches the flaps operated normally. We refueled and departed again without further problems.
