userfulness indicator Asp.net using Vb Code

I am trying to create a usefulness indicator on a page in asp.net using vb code behind. I have my reviews displaying in repeater control which has paging enabled. I have included two buttons to the end of the repeater one for Yes and the other No. I want to keep a count of how many times yes was clicked for that review and how many times no was clicked. By adding the yes count and no count together I can get the total. I can access the buttons but when I click them nothing happens. Would anyone be able to help? I've been trying to do this for hours and I can't find a solution. Below is the code I have used for both the paging and the attempt for the indicator.

Markup Code:

<asp:Repeater ID="movies" runat="server" onItemCommand="movies_ItemCommand">
        <ItemTemplate>
            <table width="641px">
                <tr>
                    <td>
                        <span style="font-weight:bold;font-size:16px;">
                        <%# Container.DataItem("MovieTitle")%>
                            </span>
                    </td>
                    <td>
                        <span style="float:right;">
