SYMPTOMS
If you are saving a template that was created by using the Template Wizard in Microsoft Excel, you may receive the following error message

Unable to write data to database. Make sure database is not protected and has valid field data-types.

and you cannot save data to the database.



CAUSE
This problem occurs when all of the following conditions are true:


 * You are saving your data to a Microsoft Access database. -and-


 * One of the fields in your Access database is linked to a worksheet cell that contains a formula. -and-


 * The formula returns a null string ("").



WORKAROUND
To work around this problem, modify the worksheet formula so that it does not return a null string ("").

For example, if the worksheet contains the following formula A1: 1  B1: =IF(A1=1,"","not 1") and cell B1 is linked to a field in your database, you receive the error message when you try to save data. To prevent the message from appearing, change the formula in cell B1 to the following: =IF(A1=1," ","not 1") NOTE: The only difference between the two formulas is that the second one contains a space between the quotation marks.



STATUS
Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.



MORE INFORMATION
The Template Wizard with Data Tracking add-in creates a template that links selected cells in a workbook to fields in a database. When you base a new workbook on the template and enter data in the linked cells, Microsoft Excel creates a new record in the database and copies the data to the corresponding data fields.
