HTM file not displaying contents - only <h even though all coding is viewable in browser

This appears to be junk code generated by MS Word which is not exactly ideal code to work with.  As @Jon Fritz said, your code contains errors denoted by the red X in a circle.  

Go to File > New > HTML and click the Create Button.

Type some text.

Save (Ctrl + S).

Does it work OK?

Going forward, when copying from MS Office, always use Edit > Paste Special with Text Only.  This strips out the junk code before it reaches your HTML document.  Use CSS to style your content.

Definitely a coding error as Jon eluded to. Somewhere there is a bad tag. However, I suspect you could end up with a lot of errors because I can see this code was generated from Microsoft Word.  Personally speaking for a quick fix, I would re-export from Word. But longer term look to make a cleaner page in DW with more modern code.

See the red "X in Circle" icon at the bottom of your document window?

That means you have errors in your html. Things like unclosed tags can cause what you're seeing in DW. Browsers are better equipped to guess what the developer was thinking when they run into code problems, DW... not so much.

Run your code through the validator here and fix the reported errors: http://validator.w3.org/nu
If it doesn't come back after fixing the problems, post back with the entire code of the page and someone here will be able to point to where things went awry.
