                Bname = Split(tempStr, ",")

                If Len(tempStr) > 0 Then

                    'MsgBox("Fname -" + Bname(0) + " L int -" + Bname(1) + " Pos -" + CStr(1 + i))

                    InsrSql = "INSERT INTO SpAuthors(USQ_RPID, F_Name, L_NameI, pos) VALUES ('" & RPID & "', '" & Bname(0) & "', '" & Bname(1) & "', '" & pos & "'"
                    ' rs = conn.Execute(InsrSql, , )

s = rs("Authors").Value is saying error Conversion from type 'DBNull' to type 'String' is not valid

s = Convert.ToString(rs("Authors").Value)

However, instead of NULL in the db field, you will end up with '' (empty string)

change

rs = conn.Execute(InsrSql, , )

to

conn.Execute(InsrSql, , )

otherwise you're tramping through the previous rs= asignment

That happens when you have a name with no comma, which causes Split to return only 1 value for Bname...
make this minor change

                tempStr = words(i)
                if InStr(tempStr, ",") < 1 then tempStr = tempStr + ","
                Bname = Split(tempStr, ",")
