Narrative:
During configuration to land at sfo on the FMS qb 28R; we were distracted with visual point out of another carrier's flight landing on 28L approximately 5 NM at our 10 o'clock position. We saw the other carrier as I was calling for flap changes and gear inside of archi around 15 NM between 6;000 ft and 2;000 ft. I did not verify the flaps were moving on the indicator until 2;000 ft cleared to land by sfo tower. I noticed they were indicating up with a slight split while the handle was at flaps 30. I executed a go-around; we ran the checklist for no flap less than 1; and used alternate leading edge extension which worked as advertised. Captain landed on 28R uneventful at gross weight of 113; at 167 ref; autobrakes 2 used until <80 KTS. All paperwork filed with company.flaps did not program from up position when handle was moved from up detent. Slight split showing on flap indicator between zero and flap position 1. I should have verified each flap setting as I called for it. Maintain aircraft control first. I will do diligence in the future. Although we were distracted by ATC and a flight that was being vectored in close proximity for a visual to 28L; that is no excuse.
