Try adding a [code=php:0]OR DIE (mysql_error())[/code] after each MySQL function to see whether it is your MySQL queries that are at fault. For example, change [code=php:0]$conn4=mysql_connect($host,$username,$password);[/code] to be [code=php:0]$conn4=mysql_connect($host,$username,$password) OR DIE (mysql_error());[/code] and do the same for the other MySQL functions and then try to run the script again to see if you get any errors.
