I know the standard code for including a file:
<!--#include file="PageTitle.asp" -->

What I want to know is how I can write this as an If statement. Example:
If (Variable = Result) Then
<!--#include file="PageTitle.asp" -->
End If

Obviously this code doesnt work. What would be a workable version?

Here is an article that can explain it to you:
