Using onChange to submit form

Hello,
I know this should be easy but I'm missing something.

I have a form like this:

    <SELECT NAME="team" onChange="submit">
            <OPTION value="Rams">Rams
            <OPTION value="Bears">Bears
            <OPTION value="RumRasin">Colts
            <OPTION value="Packers" selected>Packers
    </SELECT>

This select is actually one of 5 on the page and each select MUST go to the DB to retrieve some data.  So the first SELECT builds the menu for the second SELECT.  Right now I have OK buttons to SUBMIT but I want to change the page so that the form is automatically submitted to the action page when a user makes a selection.

This actually may be all it takes as far as the tag is concerned but what I'm missing is a javascript to go along with the onChange="submit" that I put into the SELECT.

Thanks, Jerry
