Varför funkar inte denna kod?

Varför fungerar inte denna kod i Chili!Soft ASP:

         <% if request.querystring("gbook") = "write_2" then
	Show = "SELECT * FROM gbook"
 	rs.Open Show, Connect, adOpenStatic, adLockOptimistic
    
	rs.AddNew
	
	rs("Comment") = Request.Form("field1")
	rs("By") = Request.Form("field2")
	rs("Date") = Request.Form("date2")
	if Request.Form("www") = "" then
	rs("www") = "none" 
	elseif Request.Form("www") = "www." then
	rs("www") = "none" 
	else
	rs("www") = Request.Form("www")
	end if
	if Request.Form("mail") = "" then
	rs("Mail") =  "none" 
	else
	rs("Mail") = Request.Form("mail")
	end if
	
	rs("IP") = GetUserIP()
	
	if Request.Form("irc") = "" then
	rs("irc") = "none" 
	elseif Request.Form("irc") = "#" then
	rs("irc") = "none" 
	else
	rs("irc") = Request.Form("irc")
	end if
		
	rs.Update
	rs.Close
	Response.Redirect "go.asp?gbook=view"
	else
                  end if %>

Hur ska jag få den att funka??
