I have a simple form which I want to try out (before rewriting to do
something useful)... and am having problems getting the variable to output.
From what I read I have coded it to get around the "register_globals"
being off (both on my localhost and my ISP)... but I cannot get the
variable output, below is my HTML and PHP.
Basically, the HTML file contains a form with a select box which is
supposed to pass the variable to the PHP script so it can print the result
of the variable selected.
After much searching online and head scratching, I can't find what I've
done wrong. Can anyone help?

You've got them backwards...

Compare your code and my code and try to find out what you've done
wrong. If you really can't figure it out and need more explanations feel
free to ask again.

Thanks for that... I thought it must be something simple as there was not
much code there to get wrong !!

Now with the correct PHP code, the thing works. Thanks for that :-).

Well, as you bring it up, what is the difference between the first PHP code
and the second? Which is better to use? Why? etc...

If you call the php script without posting a value for 'album' it will
throw a warning in the first case. Then it will assume, that
$_POST['album'] might be an empty string (or maybe a number with the
value 0), create the variable $_POST['album'] and output the data. You
rely on the interpreters guess, what you really wanted to do.
In the second case the script checks if it received a value and will not
output anything if there was no value.
