Well now i'm out of the beta phase I decided to make it more user friendly and i thought to place the users stats, like brave etc.. into the main menu. like on monocountry. so i copy this code over as it is required:

function userdata($ir,$lv,$fm,$cm,$dosessh=1)
$enperc=(int) ($ir['energy']/$ir['maxenergy']*100);
$wiperc=(int) ($ir['will']/$ir['maxwill']*100);
$experc=(int) ( $ir['exp']/$ir['exp_needed']*100);
$brperc=(int) ($ir['brave']/$ir['maxbrave']*100);
$hpperc=(int) ($ir['hp']/$ir['maxhp']*100);
$enopp=100-$enperc;
$wiopp=100-$wiperc;
$exopp=100-$experc;
$bropp=100-$brperc;
$hpopp=100-$hpperc;
$d="";

 

and then where appropriate i add

print "
[b]Your Stats[/b]

[b]Energy:[/b] {$enperc}%



[b]Will:[/b] {$wiperc}%



[b]Brave:[/b] {$ir['brave']}/{$ir['maxbrave']}



[b]EXP:[/b] {$experc}%



[b]Health:[/b] {$hpperc}%


 

then the error appears as:

 

Warning: Division by zero in /usr/home/ben/public_html/mafia/mainmenu.php on line 2

Warning: Division by zero in /usr/home/ben/public_html/mafia/mainmenu.php on line 3

Warning: Division by zero in /usr/home/ben/public_html/mafia/mainmenu.php on line 4

Warning: Division by zero in /usr/home/ben/public_html/mafia/mainmenu.php on line 5

Warning: Division by zero in /usr/home/ben/public_html/mafia/mainmenu.php on line 6

any ideas why? I know php doesn't allow division by zero as it is impossible. But since i copied it over from header.php where it was working i cannot see why?

The variables here are being assigned values by the "include globals.php" in the header file. so after you have cut it out from the header it's not going to be assigned any value there for 0 is assigned.
