did we get this right-mutifouls question

[stewcall]

B1 fouls A1 (A is in the double bonus)- foul called. During the Dead ball B1 pushes A1. technical foul called Players seperate- while Ref is reporting fouls- A1 and B1 fight- FlagerantTechnical fouls called on A1 and B1- both players disqualified.....

Lane cleared
1. player fouled shoots the double bonus
2 lane cleared A shoots the technical
3 A gets the ball at Mid court....
4. A1 and B1 disqualified


the question seemed to be since the last foul was a double technical for fighting--- should you go with the arrow or since the fighting fouls canceled each other ,do you go with the last point of interruption.

thanks
