have you tried document.getElementsByName("opt3")[0].value or assign an id to the select elements and do document.getElementById("opt3").value? I truly believe this solutions should be cross-browser ones...

Quick fix: Change the first two option elements of the first select element and the first option element of the second select element so that they have the attribute value="". E.g., <option value="">Size/Color</option>.

The reason is that by default, the value property of an option element has its value taken from the content of the option element. So in your case, document.form1.opt1.value is initially Size/Color.
