You need to translate some variables, for examlpe:

$dreceived = "Received $damount $dCurrency towards our goal of $dGoal $dCurrency.";
echo "<h3>Cancelled. The donation was not processed successfully. Please try again !!!</h3>";

Why do you hardcode language strings?????
Wow, just because it's not translated you gave us 1/5, what about the features?? Un-imaginable???
