How to concatenate vars for this code

I have the following code:

Event.observe($('store_locator_form'), 'submit', function() {
        $('storelocator-results').style.visibility = 'visible';
        storeLocator.search($('address').value, {
            radius: $('radius').value
        });
    });

Code (markup):

This is for a store locator script. I have it currently running off one field called "address" I need to add fields to the form and change the current address field to "city" and add "state" and "zip"
How do I concatenate the fields city, state and zip into address? I have to put it all into one because the address is all in one field in the db and address is also being run through a script for googlemaps. I have tried many ways and have been unsuccessful.

Thanks for any help!

 

you are using Prototype right? you can do it maybe like this: $('city').value + "someseparator" + $('state').value + "someseparator" + $('zip').value

 

Yes it is prototype.

That is a possible solution but how do I attach it to be the var address?

Thanks!

 

try this, this may not be the correct solution

 

SWEET! Thank you.

It worked no problem. I had the var part but wasn't getting this:

storeLocator.search(finalAddress, {
