Update Access Database Through ASP Page

I developed an ASP page which has 2 input fields- First Name and Last Name.I used Access 2002 as database. Once I click the Submit button,

it has to perform 3 tasks-----
1) It has to update the First Name and Last Name in the MS-Access database in their corresponding fields.
2) It has to go to the Home Page(which I already did)
3) It has to update the date/time in the "Time" field in the MS-Access database.

The following is the code I wrote to connect to the database and update the fields in the Access table---

<%
set MyConn = Server.CreateObject("ADODB.Connection")
set rs = Server.CreateObject("ADODB.RecordSet")
MyConn.Open "driver={Microsoft Access Driver

(*.mdb)};;DBQ=c:/documents and

settings/adcguest/desktop/webpage_html
ewsecurity.mdb;"
rs.Open sqlqry,MyConn,2,2
rs.AddNew
rs("firstname") = first name
rs("lastname") = last name
rs.update

rs.close
myconn.close
%>

Can somebody please help me in figuringout if I am missing something.
