Performing query on a table, return value is null

Hi Ahmed-samy. I am suspecting that here is something wrong with my regex method resulting in nothing was written into the table.

 string captureformat = @"\#(?'firstName'\w+)&(?'lastName'\w+)&(?'dateOfBirth'\w+)&(?'email'\w+)&(?'streetAddress'\w+)&(?'suburb'\w+)&(?'state'\w+)&(?'postcode'\w+)&(?'positionNumber'\d+)\s*";
            //matching captured format
            Regex expr = new Regex(captureformat);
            MatchCollection matches = expr.Matches(input);
            foreach (Match match in matches)
            {//storing captured format into table
                DataRow newRow = table.Rows.Add();
                newRow["firstName"] = match.Groups["firstName"].Value;
                newRow["lastName"] = match.Groups["lastName"].Value;
                newRow["dateOfBirth"] = DateTime.Parse(match.Groups["dateOfBirth"].Value);
                newRow["email"] = match.Groups["email"].Value;
                newRow["streetAddress"] = match.Groups["streetAddress"].Value;
                newRow["suburb"] = match.Groups["suburb"].Value;
                newRow["state"] = match.Groups["state"].Value;
                newRow["postcode"] = match.Groups["postcode"].Value;
                newRow["positionNumber"] = int.Parse(match.Groups["positionNumber"].Value);
            }
