I have used the Joomla Registration Plug In and I have created a form (called "Company Registration" alias co-reg) that collects all of the information for the User functionality and a lot of additional information that I required from the user (i.e. company name, address, phone number, etc.)

I want to open another form (called "Controller Registration" alias ct-reg) and have information from the "Company Registration" extended data set show in fields in this new form. Can you provide some simple script to show me how to show the company name (fieldname "Company") in this new form?

Secondly, when I submit the "Company Registration" form, I would like to add data to the "AccountNo" field (hidden field in the form) that consists of the first letter of the company name and an incrementing number. For example "Acme Co" might be "A1234" then when "Bloggs & Co" register they would be "B1235" and "Acorn Ltd" would become "A1236" when they register. Can you provide an example of how I could go about doing this?

Thanks in anticipation of your assistance.
