Hello there I was trying to modify the javascript from greybox so that it redirects to a php site upon closing...I successfully modified the script and now it redirects to any page that I choose... My next problem is that I want to pass a variable also upon closing... I cannot figure out how to do this... all the values I pass ends up showing undefined...please advise... Thanks!

this is the line that I changed:
Code:
var _2b=AJS.FORM({"method":"post","action":"GBredirect.php"},AJS.INPUT({"name":"title","type":"hidden","value":this.caption}),AJS.INPUT({"type":"image","src":this.img_close}));
The value of this.caption ends up undefined....


Here's the complete script:
