From: Kevin Bilbee on 9 Jan 2008 00:43
The error
Incorrect syntax near 'nvarchar'.
Must declare the scalar variable "@CODE".

I have looked at many posts with this error. I have potes to ASP.net forums
with no luck. How can I debug and fis this error. Below is the ASPX page the
code behind and the sql data table create schema straight from the database.

Running in windows 2003/Sql 2005 Express


Please someone fine the error, direct me tho the knowledgebase article or
something. I have used the datagrid on hundreds of forms never with an issue
but I am stumped.
