Cannot pay and make a reservation!

Hi there
suddenly my component stopped working

Now, when i try to make a reservation and pay, i've got this error:

Too few arguments to function OSBHelper::showMoney(), 1 passed in /web/htdocs/www.WEBSITE.it/home/administrator/components/com_osservicesbooking/helpers/helper.php on line 1923 and exactly 2 expected

I don't know how to fix it!

Please update, thanks!

This is the 1923 line of the file helper.php

I love your extensions, but you need to think about a better customer service...

I'm in Italy and when i write during the day, to you it's night
When you reply, i'm sleeping

So the customer service for me it's dramatic slow

Let's say that i'm not lucky at all...
