I keep getting the error must declare scalar variable "@SerialNo". Doesn't make any sense because the variable is a txt variable. This is occuring while trying to save to a sql database - cmd.Parameters.AddWithValue("@txtSerialNnumber", txtSerialNo.Text);

The expectations are probably exaggerated. Show some details about the SQL code.

There is no screenshot. Better post the code as code text.

It seems that the SQL statement, executed on SQL server by cmd.ExecuteNonQuery, contains an undeclared variable or parameter: @txtSerialNo. Maybe you should add it with cmd.Parameters.AddWithValue.

Or show details about the SQL statement.

It's very difficult to find a solution to scalar errors on the internet. All I can find is that I need to declare the scalar to "variable". I even commented out that line of code and I still get the error for the same variable, which makes no sense at all. When I type the word declare it does not appear in the IntelliSense member list so I can't use it. I've spent days on trying to figure this out and it makes me angry when microsoft's software throws these kind of errors and you can't find a solution. If you can't help that's okay. I'll just have to figure out a way around it.
