How to pass 2 variables through url

[khalid]

Hey, I am passing a variable "e" below through url and it's working:

<script>
$("#submitPlan").click(function () {
var e=document.getElementById("control_COLUMN45").valu e;
var f=document.getElementById("control_COLUMN46").valu e;

document.forms[0].action='http://www.sample.com/sign_up/Form?plan='+e+"_end";
});
</script>

When i add another variable "f" and edit the url below, it's passing both variables:

document.forms[0].action='http://www.sample.com/sign_up/Form?plan='+e+f+"_end";

But i want to use similar to this (so the url has the value for plan and plan2) and it's not working:

document.forms[0].action='http://www.sample.com/sign_up/Form?plan='+e+"_end"&plan2='+f+"_end"&;

Any help/suggestions.

Thanks!

I actually able to figure it out and it's working. Here is code that is working:

document.forms[0].action='http://www.sample.com/sign_up/Form?plan='+e+"_end"+"&plan2="+f+"_end2";

Thanks!!
