Hi Marian,
It could be the line:
$dirname = preg_replace('/[^a-z0-9]/','',$dirname);
because I'd used single quotes.
Here's it with double quotes:
$dirname = preg_replace("/[^a-z0-9]/","",$dirname);
Replace anything NOT alpha-numeric with nothing.

I tried this and it **still** didn't strip the spaces out of a name
that I gave it.
How can I make sure it strips spaces?
