jquery validation engine help

I am using Jquery ValidationEngine plugin to validate the form fields. I have the scenario when I have to validate the field that depends on the value of the hidden form variable. So the hidden variable is empty then I need the field above to required

<form id="testform" style="border:1px solid black; margin:2em; padding:1em;">
 <label for="source">Select2</label>
    <input type="text" name="txt" id="txt" class="validate[required]" value="here is my test">
    <br/>
   
<input type="hidden" name="txtHidden" id="txtHidden" value="">
    <br/><br/>
    <input type="submit" value="Submit" />
</form>

$(document).ready(function() {
    $('#testform').validationEngine();
});

by default don't add the class :
<input type="text" name="txt" id="txt" value="here is my test" />
And use :
$(document).ready(function() {
    if( $("#txtHidden").val() == "" ) $("#txt").addClass("validate[required]");    
    $('#testform').validationEngine();
});

that is not working. For example If I provide the value to txt it still submits even if there is not value in txtHidden
