Test Simple MP3 Player

My Wiki: http://wiki.scuolemodugnesi.it/∞
My folder flashtools: http://www.scuolemodugnesi.it/wiki/flashtools/∞
My file audio.php (standard) in /wiki/actions/audio.php

My file mp3 is dichiarazione.mp3

I've a file called "dichiarazione.mp3" in a directory called flashtools which is in my wiki root.
/wiki/flashtools/dichiarazione.mp3

My code is:
{{audio url="http://wiki.scuolemodugnesi.it/dichiarazione.mp3" title="Test Sound"}}
You said:
the "-16" below is based on there being 16 characters in the suffix after the wikki root
for example "wikiroot/wakka.php?wakka=" has 16 characters in "wakka.php?wakka="...if your site setup differs you must
change the "-16" to whatever the character count is.

In my case which is the count I should insert in?
change the "-16" to whatever the character count is.

I am not able to make your mods works.
Where am I wrong?
Thank you for your helping
Raffaele Paparella
