Question

In the form below, how do I get autoselect the various options based on the values of my URL parameters?

eg: http://example.com/?type=%28shirt%2C+tshirt%2C+t-shirt%29&length=25&width=17&expand=yes

        <form name="shirty" method="get">
            <select name="type" />
            <option value="(shirt, tshirt, t-shirt)">T-Shirt</option>
            <option value="(hoodie, sweatshirt)">Sweatshirt</option>
           </select>

          <select name="length" />
            <option value="select">Select a length</option>
            <option value="14">14 Inches</option>

           </select>


            <select name="width" />
            <option value="select">Select a Width</option>
