Simple AS formulation query (f5)

programming flash
1

to a frame I want to attach 2 conditions which an action has to fulfill before it can execute something.

so:

if (particularVar == Yes AND anotherniceVar == 25) {

thisfunkyMC.gotoandStop(49);

}

but obviously, this doesn’t work.

How do I have to correctly formulate it so I can put two conditions side an If statement, before something will be executed???
