Problems with INSERT to a simple Access database!

Hello!

I got a simple Access database with a table called Baskets. That table got 4 columns (id(counter), prodid(int), count(int), sessionid(int)).

I can connect to this database and do SELECT queries without any problems but when I try to do a INSERT I get an error. Below is the errormessage in Swedish:

Feltyp:
Microsoft JET Database Engine (0x80004005)
Operationen måste använda en fråga som kan uppdateras.
/webbshop/add.asp, line 23


If I translate this into english it says "The operation needs to use a question that can be updated."

The code at line 28 looks like this:
myDatabaseConnection.Execute "INSERT INTO Baskets VALUES(" & prodid & "," & count & "," & sessionid & ")"

I can not understand why I can't do a insert. Does the counter at the first column the question to crash??

The code in total looks like this:

<%
    ' Response.Status = "204 No Content"

    ' Vi läser in värden
    sessionid = Session.Sessionid
    count = Request.Form("Antal")
    prodid = Request.Form("ProdId")

    'Vi skapar databaskopplingen
    Set myDatabaseConnection = Server.CreateObject("ADODB.Connection")

    'Vi skapar den virituella sökvägen till databasfilen
    databasePath = "Databas/myshop.mdb"

    'Vi skapar en sträng med alla parametrar för databasen
    connectionString = "PROVIDER=Microsoft.Jet.OLEDB.4.0;DATA SOURCE="
    connectionString = connectionString & server.mappath(databasePath) & ";"

    'Vi öppnar kopplingen till databasen
    myDatabaseConnection.Open connectionString

    'Vi ställer frågan
    myDatabaseConnection.Execute "INSERT INTO Baskets VALUES(" & prodid & "," & count & "," & sessionid & ")"


    'Vi stänger alla databasobjekt
    myDatabaseConnection.Close
    Set myDatbaseConnection = Nothing

%>


Please help me out!

Best regards
