We made a kiddush from tzedokoh money for a yosom what should be done with leftovers ? If given money to transfer to gaboei tzedokah and one time unsure if gave or if misplaced the money what to do?

1) The Shulchan Aruch Yoreh Deah 249;16 states that the most fitting place for a gabai tedaka to give tedaka money is the important mitvah of helping yesomim marry. 2) whoever received money and is not sure what he did with it is responsible and should replace it. Rabbi Moshe Klein
