Javascript 未捕获引用错误：[生成函数]未定义

我网页上的所有链接都没有生成JavaScript函数。我运行了JavaScript控制台，所有JavaScript函数都出现了一个未捕获的引用错误

<div style="text-align:center; margin:5px; ">
<form name="jumpDriver">
  <select name="menu1" onChange="MM_jumpMenu('parent',this,0)">
    <option value=""> - Select a Schedule - </option>
    <?php
    $sql = 'SELECT `description`,`group_id` FROM `t_sched_groups` WHERE `status` > 0 ORDER BY `group_id` DESC';
    $stmnt = $db_transpo->prepare($sql);
    $stmnt->bind_result($description,$groupid);
    $stmnt->execute();
    while ($stmnt->fetch()) {
        if (isset($_GET['groupid']) AND $_GET['groupid'] == $groupid) {
            echo '<option value="?coord=editSignupStruct&amp;groupid=',$groupid,'" selected>',$description,"</option>\n";
        } else {
            echo '<option value="?coord=editSignupStruct&amp;groupid=',$groupid,'">',$description,"</option>\n";
        }
    }
    $stmnt->close();
    ?>
  </select>
</form>

如果你需要任何额外的代码，请让我知道。谢谢你的帮助

声明函数generateAddForm的代码

    //Function for generating 'add new line' form.
    function generateAddForm(spanid,tableid) {

声明的函数在哪里？Javascript页面中定义的“生成”函数在哪里？我添加了其中一个generate functions@qterniones的声明，它没有被记录为未定义。我忘记将其添加到我的原始帖子中，它也有相同的引用错误
