Need help in AS2.0 load order of MCs

I have a menu which has “home | about | contact | porfolio” buttons.

My main flash file loads an external MC (content_home.swf) in a blank MC called contentLoadHere at the start page which plays its animation up to frame 25 then stops.

When I press the “about” menu button, I want it to finish playing the current loaded MC from frame 26 to 30 before it loads another external MC called “content_about.swf”.

I want the same action to occur when I press the “contact and or portfolio” buttons.

Please help. How can I achieve this using AS2.0?

I hope I made sense.

Thank you in advance.
