I love Wordpress but when I get into php code my head spins.

I'm editing a theme that has a responder box but the values don't match the one's getresponse uses.

The theme sets the email value to the variable email
Get response needs this to be subscriber_email

The theme sets the name value to the variable from
Get response needs this to be subscriber_name

What line of php code do I need to make
subscriber_email = email
subscriber_name = form
ready to be sent to getresponse
Just substituting subscriber_email for email in the code distorts the theme.

It's driving me rapidly insane

Thanks

Tony
