include default.asp into my template

How do I include the whole default.asp page into a section of a template I've already made?

I have a nice user interface for my new web page and I want to add WebEx into that design. Right now I'm getting an Option Explicit error.

You should have only one Option Explicit statement in an asp page and it must be at the top. You can see that default.asp has Option Explicit statement at the top, move that line to the top of your final asp page.

Also you can use an inner frame which is an easy and quick solution:
<iframe src="wexfree/default.asp" style="width:500; height:500;" frameborder=0 scrolling=auto></iframe>

use include statements
