Ray, I have adjusted this with a workaround for now until I can find the time that will work for both of us for a support ticket seeing as I am in the UK.
The user now directs to a page where they select their name from a list which has the entry_id binding to the url... This will top for now so I can continue to develop the system, in particular the payment cart which I am having problems with as before. I have posted on another forum post we had correspondence on regarding this.
