I'm implementing a multilingual website and I have two flags that, when people click on them, submits the form and changes the language. I tried using the imagebutton but you can't assign a value to them. What do I need to use?

Here is the HTML...

HTML Code:
<form id="Form1" method="post" runat="server">
			<TABLE id="Table1" style="Z-INDEX: 101; LEFT: 8px; TOP: 8px" cellSpacing="0" cellPadding="0"
				width="760" align="center" border="1" runat="server">
				<TR>
					<TD height="60">
					    <table cellpadding=0 cellspacing=0 border=0 width=756>
					        <tr>
					            <td>
					                <asp:label id="Label4" runat="server" ForeColor="Blue"> Enter Work Order Number (or click 'Find Work Order' button to look up from list)</asp:label>&nbsp;
					            </td>
					            <td align=right>
					                <asp:ImageButton ImageUrl="images/english.gif" ID="Language" runat=server />&nbsp;<asp:ImageButton ImageUrl="images/french.gif" ID="ImageButton" runat=server />
					            </td>
					        </tr>
and on the server...

VB Code:
  1. ' check the querystring
  2. If Request("Language") <> "" Then
  3.     sLanguage = Request("Language")
  4. End If
