The error message is indicating that lblSalesWeek.Text doesn't contain something that can be parsed to a byte - perhaps it's an empty string or contains some characters which are not digits. You can substitute a byte value of 0 in the event of the input being invalid like so: byte b; Byte.TryParse(lblSalesWeek.Text.Trim() out b); paramCol[2].Value = b;
