Iam having some trouble with some XML code.

I downloaded Gufolks 1.11 F-22 Raptor build and i installed custom missiles on the side bay doors.

But my only problem is the missile launch sequence, which i cant get right. Because both bay doors opens but When i launch a missile the left side bay door closes while the right bay door stays open (Missile on the right bay door launches but the bay door stays open. Meanwhile the left baydoor closes with a missile still inside).

Is There any way i could fix this without using any Activate Buttons?
