Subtract currency upon adopting

[FounderSim]

I also found this in pound.php

			    $poundAdopt->dopound();
				if($this->settings->cost->active == "yes"){        
		            $cost = $this->getCost($this->adopt, "pound");
			        $mysidia->user->changecash(-$cost);
					$this->setField("cost", new Integer($cost));
			    }

Mysidia has built in function to change cash. I assume - subtracts from money. If you wanted to add money, use positive #.

$mysidia->user->changecash(-$cost);
