Would you be better off using radio buttons instead of checkboxes as per this site: http://www.echoecho.com/htmlforms10.htm?

If you want to use check boxes I guess you could do something like this:

HTML Code:

 Option 1
 Option 2
 Option 3
 Option 4

Javascript Code :

function selectOnlyThis(id) {
    for (var i = 1;i <= 4; i++)
    {
        document.getElementById("Check" + i).checked = false;
    }
    document.getElementById(id).checked = true;
}
