If you, like me, received the above error, this may be your solution.

If you used the image of the Access table in order to configure your own database then you just missed out on a few fields.
The script calls for additonal fields:
First Name Text
Last Name Text
Profession Text

The error message is caused at line 112 when the script tries writing to the field First Name and it does not already exist in the database.

If you already have the above fields but are still having the same error then one of the fields may have been misspelled in your database.

Great code, great article.
A bit better description could be useful for the database info such as a quick review on how to change it over to MSSQL, how to point to a non-local server or what happens if you need greater permissions on the folder the database is in but it can also generally be assumed that folks using code like this should have some reasonable knowledge themselves up front.

Thanks for the code.
