What is wrong with this

[Matt_T_hat]

the first few lines of my asp page are thus

<% 
Function MakeLink(LvLink)
Dim ResultIs
dim MeUrl
' Where are we?
    MeUrl = Request.ServerVariables("url")
    ResultIs = "<a Href='" & MeUrl & "?Lv=" & LvLink & "'>" & LvLink & "</a>"
    MakeLink = ResultIs
End Function
%>

it produces this:


Microsoft VBScript runtime error '800a01a8'

Object required: ''

/thehat/test/dev1/Zcon.asp, line 9


but I can not see what is wrong... anyone have an idea?
