If it doesn't work, then you need to figure out the cause of the issue. My guess is editing the wrong template.
So when you are following the steps in the link, to make sure you are looking and editing in the correct place put some place holder text.
Add THIS IS MY PLACEHOLDER, WHERE DOES THIS COME OUT????????? or some other easy text to see.
save the template, refresh the caches and go to the URL where you're expecting to see changes. If you see the
"THIS IS MY PLACEHOLDER, WHERE DOES THIS COME OUT????????" message you know your edits are working and from there you just need to make sure the code is.
