sql insert into access database requires colon

[youngnoviceinneedofh]

whats wrong with this:

Dim Cmd As New System.Data.OleDb.OleDbCommand()

        con.Open()
        Cmd.Connection = con
        Cmd.CommandText = " INSERT INTO TblContacts ('" & Night & "') VALUES " & "('Harry') WHERE (Phone = '" & incomingtextno & "')"
        Cmd.ExecuteNonQuery()
        con.Close()

it stops on the line
Cmd.ExecuteNonQuery()
telling me i need a colon somewhere. however i havent needed one in the past using sql and vb.net???
