Hi everyone,
I made a webpage in html that has a form, and instead of a button, I wanted a link. When the person clicks the link its supposed to call the code behind and do the click events I created for the link, but instead its trying to veiw the codebehind. The codebehind was done in C#. The link's href is linked with a javascript function to submit the form. The link part I think is working because its getting the submit request from the javascript so I think it's in my codebehind. I have done other pages just about like this one but they had buttons and I don't want buttons for this one. Could someone tell me what I did wrong. Any help would be appreciated. Here is the code.

html with javascript:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<script language="JavaScript" runat="server" type="text/JavaScript">

</script>

</head>
<body>

<table width="100%" height="100%" border="0" cellspacing="0" cellpadding="0">
<tr>
<td height="25" width="25" align="center"><form action="DLCounter/Downloads.aspx" name="submitform" method="post" runat="server">
<asp:linkbutton ID="lnkPLS" runat="server" Text="PLS"><a href="javascript: submitform()">Preschool's Learning Suite (PLS)</a></asp:linkbutton><br>
<asp:linkbutton ID="lnkLYA" runat="server" Text="LYA"><a href="javascript: submitform()">Learning Your Alphabet</a></asp:linkbutton><br>
<asp:linkbutton ID="lnkLYC" runat="server" Text="LYC"><a href="javascript: submitform()">Learning Your Colors</a></asp:linkbutton><br>

Use Visual Studio, look at the page in [Visual] and double click on the link. It will take you to the codebehind area and generate any code needed for it to work.
