Problem with Artist Directory: Warning Message! Please Help

[LaBella]

Hello there!
My name is Ana and I am using MAMBO SOURCE for a blog. :-)
I want a type of Music Library and I think I found it in Artist Directory.

I tried to install it today, and I thought everything was going smoothly till I previewed it on my FrontPage {my blog}.
And I get the Warning Messages. Such as:

Warning: Division by zero in /home/analilia/public_html/mambo/components/com_artistdirectory/artistdirectory.php on line 150

Warning: Division by zero in /home/analilia/public_html/mambo/components/com_artistdirectory/artistdirectory.php on line 237


Warning: Division by zero in /home/analilia/public_html/mambo/components/com_artistdirectory/artistdirectory.php on line 237

Does anybody know why I'm getting this message? Or have an idea why..?
I'm new to Mambo so... please bear with me...
I'm trying my best...
Also, another question, do I have to upload the media files through the component itself? for Ex. an MP3 song..?

Thank You Very Much,
Ana

You can View my Artist Directory at My Blog :
