Data type mismatch in criteria expression

Kdo mi lahko kaj pomaga glede te napake. Pojavi se namreč le ko je v bazi tabela orders popolnoma prazna, ko pa je v njej že kak podatek pa deluje dodajanje novih podatkov normalno.
Jamra okrog te kode:

orn=OrderNo()
For Each Key in dictCart

SQLstmt = "INSERT INTO orders (sid,orderno,customer,adate,code,qty,price,shipping,shipcode,description,username,card)"
SQLstmt = SQLstmt & " VALUES ("
SQLstmt = SQLstmt & "'" & sid & "',"
SQLstmt = SQLstmt & "'" & orn & "',"
SQLstmt = SQLstmt & "'" & customer & "',"
SQLstmt = SQLstmt & "'" & date() & "',"
SQLstmt = SQLstmt & "'" & key & "',"
SQLstmt = SQLstmt & "'" & dictCart(Key) & "',"
SQLstmt = SQLstmt & "'" & GetItemPrice(Key) & "',"
SQLstmt = SQLstmt & "'" & shipping & "',"
SQLstmt = SQLstmt & "'" & shipcode & "',"
SQLstmt = SQLstmt & "'" & description & "',"
SQLstmt = SQLstmt & "'" & username & "',"
SQLstmt = SQLstmt & "'" & card & "'"
SQLstmt = SQLstmt & ")"

Set RS = conn.execute(SQLstmt)

Next
response.cookies("qty") = 0
response.cookies("ord") = orn

Kaj je narobe, prosim vas za pomoč?

OwcA: kako bi pol ti izpeljal ta sql stavek....neki so mi že pomagal na ostalih forumih, pa je blo s temi narekovaji sam se huje :)

Kaj pa mogoce to, da tabela orders nima primarnega kljuca....al zakwa ta stvar ne deluje samo v primeru, da v tabeli ni nobenga recorda
