    Adding JavaScript Arrays and alerting user

    Hi,

    I have a group of drop down lists. Can someone show me how to put each select name into an array and if field43[] + field44[] + field45[] + field[]46 is greater than 9, then an alert will tell the user that you can only choose a total count of 9 cases.

    HTML Code:
    <tr class="product-detail">
                    <td width="25%">BD Ultra-Fine&trade; 3/10mL half scale</td>
                    <td width="25%">31G x 15/64" (6mm)</td>
                    <td width="15%">324943</td>
                    <td width="10%"><select name="field43">
                        <option value="" selected="selected">--- Select ---</option>
                        <option value="1 Case">1 Case</option>
                        <option value="2 Cases">2 Cases</option>
                        <option value="3 Cases">3 Cases</option>
                        <option value="4 Cases">4 Cases</option>
                        <option value="5 Cases">5 Cases</option>
                        <option value="6 Cases">6 Cases</option>
                        <option value="7 Cases">7 Cases</option>
                        <option value="8 Cases">8 Cases</option>
                        <option value="9 Cases">9 Cases</option>
                      </select></td>
                  </tr>
                  <tr class="product-detail">
                    <td>BD Ultra-Fine&trade; 3/10mL</td>
                    <td>31G x 15/64" (6mm)</td>
                    <td>324942</td>
                    <td><select name="field44">
                        <option value="" selected="selected">--- Select ---</option>
                        <option value="1 Case">1 Case</option>
                        <option value="2 Cases">2 Cases</option>
                        <option value="3 Cases">3 Cases</option>
                        <option value="4 Cases">4 Cases</option>

                  </tr>
                  <tr class="product-detail">

                      </select></td>
                  </tr>
                  <tr class="product-detail">
                    <td>BD Ultra-Fine&trade; 1mL</td>
                    <td>31G x 15/64" (6mm)</td>
                    <td>324940</td>
                    <td><select name="field46">
                        <option value="" selected="selected">--- Select ---</option>
                        <option value="1 Case">1 Case</option>
                        <option value="2 Cases">2 Cases</option>
                        <option value="3 Cases">3 Cases</option>
                        <option value="4 Cases">4 Cases</option>
                        <option value="5 Cases">5 Cases</option>
                        <option value="6 Cases">6 Cases</option>
                        <option value="7 Cases">7 Cases</option>
                        <option value="8 Cases">8 Cases</option>
                        <option value="9 Cases">9 Cases</option>
                      </select></td>
                  </tr>
    Also, if they try to choose more than a total of 9, they shouldn't be able to.
