Looping an animation in Flash CS5 AS2

Hello,

I’m hoping someone might be able to help me with something I can’t figure out how to do:

I have a flash banner that contains 370 frames. I want the banner to loop 2 times and then after that play from frames 1 to 88 and then stop.

As you may have guessed, I’m a beginner and would greatly appreciate any help/advice!

Just to let you know, I’m using Flash CS5 and ActionScript 2.

Thanks in advance!
