Thanks Ray.. school boy errors!!
Now I've got the data being inserted. I now have a problem with an email behaviour that gets triggered at the end of the form submit from "quote-result.php". This was working fine before the MySQLi updates.
The email body ( blank_6.php ) uses some database bindings from a recordset. I wasn’t sure how to update the bindings for the correct code so I have pasted the connection file code and rsobj file code directly into the email body file with the recordset code.
I have tested with and without the PHP/MySQLi code so I don’t think its the bindings that is effecting the mail sending.
I have tried ‘mail’ and ‘SMTP’ methods from the email behaviour.
