SQL server issue

/usr

When I try to do an INSERT command and insert text into a field, I get an error.

'The name "XXXX" is not permitted in this context.'

Where XXXX is whatever string I pass in. If I use numbers, however, the INSERT command will work just fine.

All data types are correct (String in VB, varchar in SQL) and I can manually place a text string in a field of the database, it just errors out when I try to do it through code.

strSQL = "INSERT INTO tbl72308i (MPS,Model) VALUES (" & strMPS & ", " & strModel & ")"
        aCommand.CommandText = strSQL
        Try
            aCommand.ExecuteNonQuery()
        Catch ex As Exception
            MessageBox.Show(ex.Message.ToString)
        End Try

Any ideas?

/usr

Nevermind.
