total newbie (asp into existing html page)
I know absolutely nothing about ASP.
I had a page writen for OPC communication in HTML that worked for me, but now I'm being told that I need to use ASP instead. Can anybody tell me how to make the below HTML page work with the (more) below ASP tags?
Thanks!

<body>
<input type="button" value="Get readings" name="B3" onClick="doRead();"><br>
Signal Quality: <input type="text" name="T1" size="20">

<script language="javascript">
function doRead()

try
{
var opcWebClient = new ActiveXObject("OPCLabs.EasyDA3.0");
var valueTimeQuality = opcWebClient.ReadItem("74.208.99.113", "M2MOPC.OPC.1",
"MSC:[MobilFoamSafe1]SignalQuality", "", 0)
document.all.T1.value = valueTimeQuality.Value;

Dim objVTQ As VTQ3 = objOWC.ReadItem ("74.208.99.113", _ 'Computer IP where the OPC Server resides
"M2MOPC.OPC.1", _ 'OPC Server Prog ID
"MSC:[MobilFoamSafe1]SignalQuality") 'Tag name
Response.Write("Value:" & objVTQ.Value & "<br>")
Response.Write("Qlty:" & objVTQ .Quality & "<br>")
Response.Write("Time:" & objVTQ .TimeStamp & "<br>")
Catch ex As Exception
Response.Write("Error: " & ex.Message)
End Try
