Error Code: 1054. Unknown Column '<column name>' in 'file list'

[kevin hogan]

I created a table (policybilltransactions) and attempted to add values via an INSERT statement, but receive the error "Error Code: 1054. Unknown column 'InstallPremium' in 'field list'".

I then used the option to edit the table, and after entering all of the values in in column, the same error occurs when I click the "Apply" button.

This is the query generated:
[
INSERT INTO `gnydirectbill`.`policybilltransactions` (`PolicyNumber`, `EndorsementNumber`, `TransEffDate`, `TransCode`, `TransSubSystem`, `TransDescription`, `DueDate`, `TotalDue`, `Surcharge`, `InstallPremium`, `InterestCharge`, `Commission`, `PaidAmount`) VALUES ('1106D00737', 0, '2011-02-10', '20', 'P', 'Renewal Premium', '2011-02-15', 3839.35, 5.00, 0.00, 671.88, 0.00, 3844.35);
]

This is the error:
[
ERROR 1054: Unknown column 'InstallPremium' in 'field list'

SQL Statement:

I installed MYSql yesterday via the MYSQL INSTALLER FOR WINDOWS and am using the Workbench, version 5.2.37CD revision 8576 on a Windows 7 platform.

As you can see I am truly a newbie and any assitance would be greatly appreciated.

Thanks.
