Access 2003 frt end attached to sql 2000 backend

I am trying to check for an existing record but cannot get past this
error,

too few parameters, expected 2

I have verified that all fields exist and tested the query.

It appears to occur on the Set Rec Line

Dim db As DAO.Database
Dim Rec As DAO.Recordset
Set db = CurrentDb
Dim qry As String


qry = "SELECT tblMedInfo.ClientID, tblMedInfo.DateEntered FROM
tblMedInfo WHERE
(((tblMedInfo.ClientID)=[Forms]![frmClients]![ClientID]) AND
((tblMedInfo.DateEntered)=[Forms]![frmClients]![LastUpdate]));"

Set Rec = db.OpenRecordset(qry, dbOpenDynaset, dbSeeChanges)

If Rec.RecordCount 0 Then
MsgBox "Record Exsist"
Else
MsgBox "Will Open And Add Record"
End If

Any Help Always Appreciated

qry = "SELECT tblMedInfo.ClientID, tblMedInfo.DateEntered " & _
"FROM tblMedInfo WHERE tblMedInfo.ClientID=" &
[Forms]![frmClients]![ClientID] & _
" AND tblMedInfo.DateEntered=#" & _
Format([Forms]![frmClients]![LastUpdate], "yyyy/mm/dd") & "#;"
