Adding HTML in HTML Not Work

Instead, tester.x is always a blank page locally (opening the file itself as c:\temp\tester.x) and externally (as IP).

I can not figure out why it keeps coming up as blank. I hope I provided enough info. What can I do to make it work with this simple code?

Thank you.
