im trying to have javascript in my header, so i dont have to re-type the attributes on every page i want a pop-up, so far this is what i have, but its not working..

There's a tutorial on TechTuts that deals with Javascript pop-ups:

Code:

<script type="text/javascript">
/*<![CDATA[*/
function win(width,height,url) {
var myfloater=window.open(url,'','scrollbars=yes,toolbar=no,resizable=yes,status=no,width='+width+',height='+height+',top='+((screen.availHeight/2)-(height/2))+',left='+((screen.availWidth/2)-(width/2))+',directories=no');
}
