I dont see form elements named CSE_phone or Record_Type on your insert page. The only one I see is Attn_To.
the Attn_To form element has been created, but you have not updated the the Insert record behavior to use it.
In the server behaviors list, double click the insert record behavior to update it. Select the Attn_To column in your database, then click the lightning bolt next to value and select the Attn_To form element.
