I tried your code and it worked but not as I expected as my previous explanation wasn't clear enough. I need the function to output the text

PHP Code:
topline.nxPos = 7
topline.nyPos =50 
into the function i.e

PHP Code:
btn1.onRollOver = function() {
topline.nxPos = 7
topline.nyPos =50
} 
using the two arrays was an attempt at cutting down the amount of code. The function currently looks like this. Which works fine but is too lengthy as there are many buttons.

PHP Code:
  _parent.portfolio_btn.onRelease = function(){
        _root.nav.topline.nxPos = 7;
        _root.nav.topline.nyPos = 20;
        //
        _root.nav.bottomline.nxPos = 7;
        _root.nav.bottomline.nyPos = 512
        //
        _root.nav.secondline.nxPos = 7;
        _root.nav.secondline.nyPos = 164;
        //
        _root.nav.thirdline.nxPos = 7;
        _root.nav.thirdline.nyPos = 368;
        
        _root.nav.no1text.nxPos = 0;
        _root.nav.no1text.nyPos = 30;
        
        _root.nav.no3text.nxPos = 0;
        _root.nav.no3text.nyPos = 378;
    } 
I hope that makes sense
