This Is Still Not working, even though I have followed the limited Instructions!!! Come On..................

Firslty let me start of by saying that even though you have a nice impressive plugin sets that becomes very useless when you instructions on how to install stuff and to get thingsa to work are unhelpful....  This is getting beyond a joke...
 
I have now been successful in getting the datepicker script to work on this page http://digitalresellersvault.com/html/admin/datepicker.html
 
However when I move it over to add it to a membership site.. The page that I am adding it to stops working..
 
I am trying to add it to the add_products.html page, I have followed all of the instructions and nothing works..
 
I now NEED to speak to someone you can help me..
