I'm currently not sure why your first piece of code isn't working, but
the second is quite simple. You aren't returning any variable in your
function, and so it won't output anything. Add the following:
return $previewtext;
Just before the }
Then it will return something, but i think not what you wanted to :(
The first piece of code isn't working cause : $previewtext != $previewstext
