Can offer negative money on trades

[fadillzzz]

Seems like people always forgot to filter the (-) minus sign.
Anyway, I think this should fix the problem.
Open your trade.php
find this code

PHP Code:

$adoptwanted = $_POST["adoptwanted"];
$adoptgiven = $_POST["adoptgiven"];
$cashgiven = $_POST["cashgiven"];
$message = $_POST["message"]; 


Just below that, add

PHP Code:

$cashgiven = abs($cashgiven);
