Javascript Get Vvariable Names From Array And Then Use

Say I have some variables setup like so;

<script type='text/javascript'>
<!--
panelsArray = new Array("form0","form3","form4","form5","blotter");
var blotter = new Array(&#3936;',&#39462;',&#39762;',&#39292;','block','');
var form0 = new Array(&#39202;',&#3955;',&#39609;',&#39185;','block','');
var form3 = new Array(&#39948;',&#3968;',&#39301;',&#39139;','block','');
var form4 = new Array(&#39861;',&#39655;',&#39400;',&#39158;','block','');
var form5 = new Array(&#390;',&#390;',&#39805;',&#39291;','block','');
// -->
</script>

and I want to parse the first array and then within that loop I want to get the variable name from the 'outer' array and then reference the contents of the array with that name... I was trying to do the following but it doesn't work, I'm obviously missing something about transmogrifying the text "form0" into a variable name...

for(f=0;f<panelsArray.length;f++) {

thisPanel = panelsArray[f];
alert(thisPanel);
thisPanelWidth = thisPanel[0]
alert(thisPanelWidth);

}
