Does your form mailer tell you to use <input type="hidden" name="GOTOURL" value="http://www.heybyrne.co.uk/contact_confirm.htm"> ? Or did the instructions come from another mailer?
The form mailer tells users to use <input type="hidden" name="GOTOURL" value="http://www.heybyrne.co.uk/contact_confirm.htm">
not other instructions were used.
Thought it would work first time but nope. If fields are left blank however the user is told about this, yet it wont redirect after send is activated.
