I have a web form created in front page for example

<a shape="rect" href="mailto:example.com/update-mail.htm?oldaddress=johndoe@example.com" shape="rect">example.com/update-mail.htm

on it is a field called eMail. I want to pass data to this field via the URL.

I have tried

<a shape="rect" href="mailto:example.com/update-mail.htm?eMail=johndoe@example.com" shape="rect">example.com/update-mail.htm?eMail=johndoe@example.com


but although we didn't get an error, it didnt appear to populate the field.

Do I need to do something else ?

Also if I wanted to pass two fields - what would the syntax be.
