I have a form with a datasource of a SQL Database table. There are no foreign keys on the table. There are 2 datetime items in the table. When I save the form, it does not get saved into the database. There is no error given. It just does not save into the database. However, if I do not include the 2 datetime fields in the form, it saves into the database just fine. I don't know if this is also possibly a culture problem as I am using EN-gb. 

.NET 4

Umbraco 4.7.1

Contour 1.1.11

Here is a copy of my sql script to create the database table:

To recreate just use this table as a datasource for a form and then fill out the form and it will not save into the database.

CREATE TABLE [dbo].[ClubOrder](

[Id] [int] IDENTITY(1,1) NOT NULL,

[Title] [nvarchar](255) NOT NULL,

[FirstName] [nvarchar](255) NOT NULL,

[Surname] [nvarchar](255) NOT NULL,

[Address1] [nvarchar](255) NOT NULL,

[Address2] [nvarchar](255) NULL,
