Appeal Play Process

[Rufus]

If mistakes are the stuff of learning I'm getting smarter than ever coaching this year.

Situation - R2, 1 out, fly ball caught by RF. R2 tags and advances to 3rd, but left early. I request time to appeal and am informed by the PU that by him granting time I've lost the ability to appeal. No problem, lesson learned (the hard way).

My question is this - I want to be sure I don't mess up again on an appeal play and teach my players the correct procedure. Would you all please help me with the correct procedure for appeal a situation like this, and then let me know if there are differences based on rule sets?

I've got the rules for OBR and NFHS, but will be honest and say I thought I understood this process before this weekend, hence my request.

Thanks in advance.
