Yet another setInterval Q

hey all,
i’ve been having trouble with an instance of setInterval that i’m using and how to reference it from other clips.

First off, am I even able to reference a setInterval from another clip (I want to clear and interval if a certain clip hits a certain frame.)

if you check out this, and go to the ‘work’ section you’ll see what I mean. Once there, click on one of the subnav’s on the bottom (Research, Strategy, etc…), once the slider mask moves to the left quickly click somewhere on the subnav again. You’ll see the whole **** clip spaz out because it’s not clearing the setInterval timer.

Is there a better way to do this?
Right now, things work like this:
A click of the nav sends the mask clip away from the content, with this click, the main content is paused with enough time to let this mask thing slide out of the way. once it’s gone, the main content goes to the frame in the clip that the newly clicked content is on.

the code on the button looks like this:

but.onRelease=function(){
        clearInterval(_parent.pauser);
        clearInterval(_parent.pauser2);
        _parent.slider.myVariable = -600 //the slider mask that slides left
        _parent.content.gotoAndStop('reset');
        _parent.pauser=setInterval(
        function(){
                clearInterval(_parent.pauser);
                _parent.content.gotoAndPlay('research');},1000);
        _parent.pauser2=setInterval(
        function(){
                clearInterval(_parent.pauser2);
                _parent.portcontent.loadMovie('projects/blank.swf');},1000);
        //loads a blank clip so as to clear anything that loads from the left navigation menu
        
};

I can send a link via email to an fla if someone needs to see more, but it’s 18mb.

any ideas on how to solve this or a better way to go about it?
