Correctable Error Question

[orangeump]

hey guys, dont post a ton here, but do read everything daily.

I was just watching a game this evening when this play occured. Just wanted to have some opinions on this play, I will give what the results were later on after a few good replies.

A1 shooting the first of a two shot foul, when after the first free throw the ball was allowed to remain live and rebounded by A3 (both teams were going for the rebound). A3 was then fouled by B1, setting up a bonus situation for A3 to shoot.

Upon calling the foul, R1 immediately conferred with R2. They then went to the table and had a discussion, seemed to come up a ruling.

I believe this is enough information to go on, please assume they figured it out at this point and what should happen next?
