ASP Error: Optimistic concurrency check..

Hi guys,

Getting a strange error message when trying to run an update query.  I'm using a cursor type of 2, and locktype of 3.  It's just a simple update query on a record that definatly exists.

----------------------------------------------------
Microsoft OLE DB Provider for ODBC Drivers (0x80040E23)

[Microsoft][ODBC SQL Server Driver][SQL Server]

Optimistic concurrency check failed. The row was modified outside of this cursor.

C:\INETPUB\WWWROOT\E-CVS\HTDOCS\NEW\JSINCLUDES\../../tomEcv/includes/stats.asp, line 503
----------------------------------------------------

Looked up on Google, it's to do with cursor and locktypes, but I'm sure im using the correct ones!

Anyone know whats wrong?

Tom
