Narrative:

Cleared for the approach; slowing through 190 KTS and descending; the captain called; 'gear down below 200 KTS; flaps 15 degrees; set speed.' as I moved the flap handle to 15 degrees I noticed the flap indicator is still at 5 degrees. I put the flap handle back to 5 degrees then tried flaps 10 degrees again; but the gage still read 5 degrees so I placed flap handle back to 5 degrees. I then called approach told them we needed to break off the approach due to a flap problem. Approach vectored us north and to maintain 4;000 ft. I pulled out the QRH and went through 'trailing edge flap disagree' procedure; checked the emergency/abnormal landing chart; set vref speed for five flaps and declared an emergency. We were then sequenced back to the ILS and landed without incident.
