网页出错，麻烦高手指点一下
老师让我们做一个注册网页，用到数据库，页面显示正确，但点击提交时出错。<%@ Import Namespace="System.Data" %>
<%@ Import Namespace="System.Data.OleDb" %>
<script language="VB" runat="server">
Sub Enter_Click(ByVal ByValSender As Object, ByVal E As EventArgs)
Dim conn As New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & Server.MapPath("userinfo.mdb"))
Dim strSql As String
strSql = "Insert Into users(user_name,password,real_name,tel_number,email) Values('" & user_name1.Text & "','" & password1.Text & "','" & real_name1.Text & "'," & tel_number1.Text & "','" & email1.Text & "')"
Dim cmd As New OleDbCommand(strSql, conn)
conn.Open()
cmd.ExecuteNonQuery()
conn.Close()
message.Text = "谢谢注册"
End Sub
</script>
<html>
<body>
<h4 align="center">注册页面</h4>
<center>
<form id="Form1" runat="server">
<table>
<tr>
