Auto_complete_field problem

Will anyone tell me why the following code is not calling
into :Controller=> portal :action=> venue_site_live_search when I
typed any characters into the text field?

I apprecated …

<%= javascript_include_tag “prototype” ,“effects” %>

<%= stylesheet_link_tag ‘autocomplete’ %>

<%= error_messages_for :team -%>

<%= form_tag(:controller => “portal”, :action =>
“fire_portal_selection” ) -%>

<table>

    <tr>

        <td style="text-align:center;">
            <img width=250 height=99 src="/images/

logo_google_suggest.gif"/>

    </tr>

    <tr>
        <td>
            <center>
                <table>
                    <tr style="text-align:center; vertical-

align:middle;height: 50px;">

                        <td style="width: 80px;">

                            <%= text_field "portal",

“searchtext”, :size => 40 -%>

                            <img id="ajax-loader" src="/images/

ajax-loader.gif" style=“display:none;”/>

                            <%=

auto_complete_field :portal_searchtext,
:url =>{ :controller => “portal”,
:action=>“venue_site_live_search”},
:frequency => 0.2,
:indicator =>“ajax-loader”,
:token =>"," -%>

                        </td>

                    </tr>
                </table>
            </center>
        </td>
    </tr>

    <tr>
        <td>
            <div class="auto_complete"

id=“portal_searchtext_auto_complete”>

            </div>

        </td>
    </tr>

    <tr/>
    <tr/>
    <tr/>

    <tr>
        <td style="text-align:center;">
            <%= submit_tag(:Welcome) -%>
        </td>

    </tr>

</table>


<% end_form_tag -%>
