为什么我的提交按钮没有提交？

Question

这似乎是一个非常愚蠢的问题，但出于某种原因，我的提交按钮并不是在进行任何提交。我希望我错过了一些明显的东西。我正在使用Zend表单，这就是输出的显示方式：

<form id="uploaderForm" enctype="application/x-www-form-urlencoded" action="/account/new/excel-file-upload" method="post">

<div id="uploaderDialog">
    <ol id="steps">
        <li id="step1">Download our template</li>
        <div class="stepDetails">
            <a href="#" id="clickHere">Click here</a> to download an Excel template.
        </div>


        <li id="step2">Fill it out with your students' account details</li>
        <div class="stepDetails">
            <p>Just be sure to include each student's first name, last name and email address. Assign them a Fisdap username and password, then save the document
            to your computer.</p>
        </div>


        <li id="step3">Upload to Fisdap</li>

        <div class="stepDetails">
            <p>Use the "choose file" button below to find your document, then click "Upload". We'll take it from here and activate each of your student
            accounts.</p>
        </div>

        <div id="fileInput">
            <div id="fancyFileInput">
                <div class="extra-small gray-button"><a id="chooseFile" href="#">choose file</a></div>
                <div id="fileName"></div>
            </div>
            <div id="inputFix"></div><dt id="file-label">&#160;</dt>
            <dd>
            <input type="hidden" name="MAX_FILE_SIZE" value="33554432" id="MAX_FILE_SIZE">
            <input type="file" name="file" id="file"></dd>
        </div>

    </ol>

    <div id="inputFix"></div><dt id="testing-label">&#160;</dt>
    <dd id="testing-element">
    <input type="text" name="testing" id="testing" value=""></dd>

<div id="buttons">
    <div class="small green-buttons">
        <div id="uploadContainer">
           <dt id="uploadSave-label">&#160;</dt><dd id="uploadSave-element">
               <input type="submit" name="uploadSave" id="uploadSave" value="Upload" class="green-buttons"></dd>                <!--<a id="uploadButton" href="#">Upload</a>-->
        </div>
    </div>

    <div class="small gray-button">
        <a id="cancelButton" href="#">Cancel</a>
    </div>
</div>

对我来说似乎很简单。此表单不在任何其他形式内，并且没有JavaScript / JQuery阻止表单提交。我不知所措。有任何想法吗？提前谢谢！
