Polish and Israeli Currency

There is a bug with currency ID, thats why Polish Zloty is not displayed in currency select form.
It is located in easyReservations_admin_settings.php file, line 251.
Bug looks like that: ‘#122;&#322’ => ‘Polish Zloty’,’#122;&#322′ => ‘Israeli Sheqel’.
ID #122 is a key for both Polish and Israeli currency.
I do not know which ID should have each of currency, but removing Israeli Sheqel key and value lets me display Polish currency.

Thanks for reporting.
That bug is already fixed in the beta.
