Need help with timers

Hello everyone. This place is great, so I’m going to ask nicely if some of you guys can help me out with this. I have checked in some deep corners of the internet to find answers to this, I somehow got a bit of what I wanted to work, I’m just out of solution, being a total Action Script amateur myself.

Problem: I have the MC playing around like it’s on drugs, since there are no delay set to it (I have no clue how)

What I need: The MC to get a random timer before it plays, then once it has finished playing, repeat the timer again and etc…

Here’s the FLA (see attachment) if you want to check it out, I’d be really grateful if someone could take it from there and make it work using the master MC from that flash.

I had to ZIP it since it was around 160 KB.
Thanks for your time.
