Simple:
Change the 100s in:
$enopp=100-$enperc;
$wiopp=100-$wiperc;
$exopp=100-$experc;
$bropp=100-$brperc;
$hpopp=100-$hpperc;
$gymopp=100-$gymperc;
To your desired width then change the 100s in:
$exp_needed=(($ir['level']+1.5)*($ir['level']+1.5)*($ir['level']+1)*2.7);
$enperc=(int) ($ir['energy']/$ir['maxenergy']*100);
$wiperc=(int) ($ir['will']/$ir['maxwill']*100);
$experc=number_format(($ir['exp']/$exp_needed*100), 2);
$brperc=(int) ($ir['brave']/$ir['maxbrave']*100);
$hpperc=(int) ($ir['hp']/$ir['maxhp']*100);
$gymperc=number_format(($ir['gymxp']/$ir['gexp_needed']*100), 2);
to the smae desired width understand?
That should work
