Making a Kirupa Tutorial

I am having trouble making a tutorial for Kirupa. This is a flash tutorial, and involves a Flash example. So, When I took the example tutorial
http://www.kirupa.com/resources/tutorial.htm
I took out the vibration picture.
Note that I am using MS Word to edit the htm file.
So, I went to Insert>Object… did from file and selected my swf file. It showed up as a square box with an X (not the red one, took upt the whole spot) in the edit screen. However, when I did Web Page Preview, it didn’t show up. I am a complete novice at html, so I don’t know what I did wrong. I thought it would be embedded in the file or something.

Also, the box showed up as small and square, though my swf file is 400 x 300.
