5-second closely guarded rule

[Coach Bill]

Could someone please post the NFHS 5-second closely guarded rule?

We had a minor to-do in our boys middle school game. According to the league rules on the website, we were playing NFHS rules, but a league official at the game said that as long as the playing was dribbling - there was no 5-second count. So, the refs didn't call it. It was pretty comical at times. A few times we had one of their ball handlers closely guarded for 8-9-10 seconds. I argued the first time, but that's when the refs told me I was right, but this league doesn't go by that.

I think the league official is confused with international rules, or NCAA or is the girl's rule different with a shot-clock?

Anyway, I'd like to send them the text of the rule. So, if someone could help, I'd appreciate it. Thanks!
