Flash Button Headache

i am designing a site in a way that i call use actionscript to load movie clips onto the stage in levels, but i am having tons of trouble with the buttons.

I want the buttons to look different (my over state) when you are on a particular page eg: if you are on the contact us page, the contact button will be purple. i cant seem to be able to do this. i saw a file that had this done, but i can not figure it out. here is the code for the button i saw (this is not my code):

on (release) {
if (_root.link<>num) {
_root[“item”+_root.link].s_menu.gotoAndPlay(“s2”);
_root[“item”+_root.link].gotoAndPlay(“s2”);
for(j=1;j<6;j++){
_root.ykoord[j]=_root.K[j];
}
_root.link = num;
for(j=num+1;j<6;j++){
_root.ykoord[j]=_root.K[j]+b._height;
}
s_menu.gotoAndPlay(“s1”);
getURL(“index-1.html”);

}

My flash file is located here http://www.lucidigital.com/suite.zip (372KB), please anyone who can please, please, please help me. I am running out of time on this project.
Thank You
