How to insert HTML into sidebar

Hi there,

I have a weather page: http://www.dansmith.ca/weather

And I want to put a small box with the current conditions into the sidebar, but not sure how to go about doing it. I tried Satollo’s “Include-It” but can’t figure it out. It’s highly rated, but the documentation is very poor.

The file containing the current weather stats is a small HTML file called temperature.htm.

Can anyone fill me in on how to accomplish this? I’ve struggled with it for a short while now and am getting a bit frustrated.

I can get it to display as a normal page, but not in the sidebar. You can see what I already have at: http://www.dansmith.ca/blog/?page_id=322

Many thanks,
Dan
