How to jump back to a specific frame in previous swf

dreeft’s suggestion at http://www.kirupa.com/forum/showthread.php?t=92245 sounds great but i’m having a helluva time getting it to work.

i have a clip that i split into 2 separate “slide show style” swf files because of the size. i’ll call them firstHalf.swf and secondHalf.swf. in firstHalf.swf, i labeled the last frame, “last”. in secondHalf.swf, i labeled the last frame, “jumpBack”.

i have buttons that link the previous and next frames in each swf.

i am trying to get the “previous” button from frame one of secondHalf.swf to link back to the last frame of firstHalf.swf.

on the button instance of this “previous” button in secondHalf.swf, i placed the following action:

on(release){
_root.gotoAndPlay(“jumpBack”);
}

i created a keyframe in the last frame of secondHalf.swf and labeled it “jumpBack”. i created an empty movie clip symbol, named it “prevMC_mc” and dragged this empty movie clip symbol into this “jumpBack” frame and gave it an instance name of “prevMC_mc”. i then selected this instance and entered the following action to the movie clip instance:

onClipEvent(enterframe){
this.loadMovie(“firstHalf.swf”);
this.gotoAndPlay(“last”);
}
//targeting the last frame of firstHalf.swf

when i do a control > test movie for secondHalf.swf, the “previous” button on frame one of secondHalf.swf doesn’t work. it simply refreshes to frame one of secondHalf.swf.

if i add stop (); to the jumpBack frame in secondHalf.swf, the “previous” button takes me to firstHalf.swf, but to the first frame, rather than the last frame.

i apologize if my description of the problem is confusing. can anyone offer suggestions? thank you very, very much!
