    <select name = "Movie"> 
    <option value = "">Select One</option> 
    <option value = "I am Legend">I am Legend</option> 
    <option value = "Wedding Crashers">Wedding Crashers</option>

    have your select one option set to be automatically selected. give it an on change event and enable the other "SELECT" as long as Movies value is not equal to ""
