onChange not sending the desired value, minor debug assistance needed

Attached code snippet.

When the user changes the value of the <SELECT> element, I want to send the VALUE of the selected element (i.e., https://secure.url.com, etc.) to the changeimage function, which in turn displays a different image in the <IMG> tag identified by "imagea".

The way I have it now, it is returning something like "[object%20HTMLSelectElement]" to the function instead.

I'm sure there is just something that isn't quite right that is very easy to fix. Thanks!
