Javascript not playing well with PHP in dropdown list

[mpinter09]

Thanks for dropping in.

I have a large drop down menu that I have eliminated the "enter" button from by using Javascript. The menu displays table entries stored in a PHP document.

The JS script is working fine and communicating with the PHP doc but the communication is flawed. Instead of grabbing the correct link, I get returns like this:

[03:11:42.034] GET http://projectrepresentme.com/county...e%3D=Calaveras [HTTP/1.1 200 OK 215ms]

All this stuff (%3E%0D%0A%0D%0A%3Coption+value%3D=) is URL gibberish and doesn't belong.

The correct URL should be http://projectrepresentme.com/county...php?=Calaveras

Does anyone know how to remedy the situation?

Here's a link to the test page: http://projectrepresentme.com/testpage/

Thank you!
