how can i check for cookies

[jmeckley]

I have a need for a simple cookie. When a user clicks a link to vote I want the code to check for a cookie. if the value of the cookie is true, do not let the person vote (1 vote per person). Else allow the person to vote and place a cookie on their box.

My code doesn't seem to be working. Any thoughts?

If IsDBNull(Request.Cookies("PplsChoice")) Then
            Dim Cookie As New HttpCookie("PplsChoice")
            Dim Item As String = Request.QueryString("i")
            Dim cmd As New ExecuteCommand(AppSettings("cnn") & Server.MapPath("\GalleryCatalog\DataSource\TEST_auction_data.mdb"))
 
            'update catalog table
            If cmd.SetData("UPDATE Catalog_tbl SET PplsChoiceTally = [pplschoicetally] + 1 WHERE ItemNumber = '" & Item & "'") Then
                'append cookie to flag the computer's vote
                Cookie.Expires = #4/16/2004#
                Cookie.Values.Add("Voted", "True")
                Response.Cookies.Add(Cookie)
                lblVote.Text = "Thank you for casting your vote for People's Choice the results will be determined on " & AppSettings("Date.PplsChoice")
                lblVote.ForeColor = Green
            Else
                lblVote.Text = "We're sorry, your vote was not tallied, please try again. If the problem continues contact WITF to cast your vote."
                lblVote.ForeColor = Red
            End If
        Else
            lblVote.Text = "We're sorry, our records show you have already casted a vote for People's Choice."
            lblVote.ForeColor = Red
        End If
        lblVote.Visible = True
