Operation must use an updatetable query

I got the following error when trying to insert some data into a database.

Error Type:
Microsoft OLE DB Provider for ODBC Drivers (0x80004005)
[Microsoft][ODBC Microsoft Access Driver] Operation must use an updateable query.
/toets/include/functions.asp, line 209

I just moved my site to another pc with WinXP Pro and ISS and since then i get the error. I didn't get it on my old pc with the same specifications. I set the database directory to allow:
script source acces, read and write
The same as before..

So whats the problem? Can anyone help me.

Read the Database FAQ on this site and follow the steps word for word.  That should fix your problem.

Cheers,
Andrew
