Can't add accessories to my products

[phantom309]

Hi I have been having problem when I try add accessories to my products in the

Associations section of products nothing shows up when I start typing I have ran a viewed source code and I found that on the site that I am having problems with there is missing code but I don't know where that file is located at so I can edit it

 

Below is the code of the site that is not working

 

 

<p style="clear:both;margin-top:0;">
                        <input value="" id="product_autocomplete_input" type="text">
                        Begin typing the first letters of the product name, then select the product from the drop-down list.
                    </p>

 

and below is the code from a working site

 

                        <input class="ac_input" autocomplete="off" value="" id="product_autocomplete_input" type="text">
                        Begin typing the first letters of the product name, then select the product from the drop-down list.
