Function not working

I am using a function which gives each users the money for the percentage they earned.

But it just seems to add nothing to their money
Here is the part of the code that does it...

$ocmoney1 = rand(130000,160000);
$cash = $total * 70000;
$cashed = $cash / 2;
$cashs = rand($cashed, $cash);

$lmoney = ($cashs / 100) * $l_price;
$wemoney = ($cashs / 100) * $we_price;
$eemoney = ($cashs / 100) * $ee_price;
$dmoney = ($cashs / 100) * $d_price;

$leader_money = $fetch->money + $lmoney;
$we_money = $we->money + $wemoney;
$ee_money = $ee->money + $eemoney;
$driver_money = $driver->money + $dmoney;

mysql_query("UPDATE users set money='$leader_money' WHERE username='$username'"); 
mysql_query("UPDATE users set money='$we_money' WHERE username='$oc->we'"); 
mysql_query("UPDATE users set money='$ee_money' WHERE username='$oc->ee'"); 
mysql_query("UPDATE users set money='$driver_money' WHERE username='$oc->driver'"); 

PHP:

The money section is 'decimal' - 0,65

What is wrong with this?

Thanks
