Passing a variable to HTML tag

Hi,

I'm creating a control to get the next and back page name. When I try to pass that name to the href tag in the HTML, the link is empty and I'm not sure what's wrong. I've checked the values with response.write so I know that the values are there. I've also defined the PageBack and PageNext variables outside the sub.

<%@dotnet.itags.org. Control Language="VB" %>
<script runat="server">
 Dim PageBack as String
 Dim PageNext as String
 Sub Page_Load(sender As Object, e As EventArgs)
 Dim strPageName = System.IO.Path.GetFileName(Request.Path)
 Dim PageNumStart as Integer = strPageName.Indexof("P") +2
 Dim PageNumEnd as Integer = strPageName.Indexof(".")+1
 Dim PageNum as String = Mid(strPageName,PageNumStart,PageNumEnd-PageNumStart)
 PageBack=Left(strPageName,PageNumStart-1)&PageNum-1 &".aspx"
 PageNext=Left(strPageName,PageNumStart-1)&PageNum+1 &".aspx"
 End Sub
</script>
Back<br>
Next

I've also tried the href with just the double quotes: ="<%# PageBack %>"
ThanksYou need to call DataBind() at the end of your Page_Load.
Thanks so much. I normally do but forgot it here.
