It's hard to know without seeing the script and what it's trying to do. Typically, if the SQL server is placed at the same machine as the web server, you'd connect using localhost or 127.0.0.1 instead of the machine name.
Edit the script and look for something like
mysql_connect("speakhost", "yourusername", "yourpassword") or die(mysql_error());
and change it for:
mysql_connect("127.0.0.1", "yourusername", "yourpassword") or die(mysql_error());
As I said, it's really hard to know without further information. Hope that helps.
P.S. I just checked your site and there does not seem to be any content on it.
