How do I setup this validation. Sel1 is always required. If sel1 == 0, then sel2 must be > 0. If sel1 > 0, then sel2 can be anything.
<select id="sel1" name="sel1" class="required"> <option value="></option> <option value="0">0</option> <option value="1">1</option> <option value="2">2<option> </select> <select id="sel2" name="sel2"> <option value="0" selected>0</option> <option value="1">1<option> <option value="2">2<option> </select>
