$("value") is null -> jQuery

I am trying to implement client side validation using jquery form validator but I have followed the guide and also noted in googling the answer to my question that there can be clashes with prototype.js I have added the line var JQuery = jQuery.noConflict(); into the bottom of my jquery-1.5.1.min.js file.

Firebug is still saying $("#contact") is null $("#contact").validationEngine();

I have the required javascript and jQuery code loaded into my main page template.php file witch then calls a view called contact.

Contact Page View:

 <section id="content" class="contact-us">
        <h1>Contact</h1>

<div id ="formLayout" class="contactForm">

<section id = "validation"></section>

<form action=contact" method="post" accept-charset="utf-8" id="contact" name="contact">

<fieldset>

<label><label for="name">Name:</label><span class="small">Required Field - Text</span></label>

<input type="text" name="name" value="" id="name" class="validate[required[custom[onlyLetterSp]]]"  />

<div id="error"></div>

<label><label for="email">Email:</label><span class="small">Required Field - yourname@example.com</span></label>

<input type="text" name="email" value="" id="email" class="validate[required[custom[onlyLetterSp]]]"  />

<div id="error"></div>

<label><label for="phone">Phone:</label><span class="small">Required Field - 021214589</span></label>

<input type="text" name="phone" value="" id="phone" class="validate[required[custom[onlyLetterSp]]]"  />

<div id="error"></div>

<label><label for="message">Message:</label><span class="small">Required Field - Text</span></label>

<textarea name="message" cols="90" rows="12" id="message" class="validate[required[custom[onlyLetterSp]]]" >

</textarea><div id="error"></div>

<input type="submit" name="submit" value="Submit"  />

</fieldset>

</form>

</div>  

    </section>
</div>
    <div class="clear"></div>

change it to

jQuery("#contact")

the .noConflict() removes the $ binding to jQuery

If you have...

var JQuery = jQuery.noConflict();

...then...

$("#contact") is null $("#contact").validationEngine();

...will always be the case, as $ doesn't point to jQuery anymore. Try jQuery or JQuery there.

The latter one only works because you assigned the new identifier of jQuery to JQuery. I wouldn't bother doing that personally, as jQuery is consistent and your different case version will probably only lead to confusion.
