Did I get it right? She only got one FT

[DC_Ref12]

This morning - girls game - middle of the first half, and Team A's coach has been barking at me and my parnter the whole time. His team is called for a 5-second OOB violation and he is furious and calls us both "complete morons" at the top of his lungs when I'm right next to him. *WHACK*

My partner goes to administer the FTs and mistakenly tells the players 1 FT (I wasn't paying close enough attention)....B1 misses the FT and my partner gives Team A the ball and they inbounds. At this point, I note to myself that she should get another FT. But he ball is in play now, Team A misses a shot at their goal, Team B rebounds, comes back down and makes a layup. I stop the clock and alert the benches that Team B has an unawarded FT.

B1 shoots her second FT, after which Team A gets the ball OOB under Team B's basket.

Did I make the right call? Should I have stopped the play as soon as the ball became live? Should I have waited for the next dead ball?

Thanks.
