When I press Submit ( pay now ) button it doesn't pick an email address from my form ( http://parkingatairport.co.uk/index.php/bristol-airport-parking-bookings )
By the way your attachment not working correctly ( cannot attachjpg or png file - The file cap.JPG, which you are attempting to upload is in an unsupported format!!!! )
Hope you can help to resolve this issue
