Hi. Judging from what I see your problem might be: a) The name of the variable is not OK. b) Variables are declared so: type var-name. Hope this helps.

This error is telling you that Sql Server does not know about the SQL variable '@Marks1'. Are you attempting to call a stored procedure in this code? It sounds like the error is probably in that rather than in your C#... Regards, Rob Philpott.
