On what side has the Mezuza got to be? What Blessing is made when placing the Mezuza?
A mezuzah scroll is affixed to the doorpost on the right side when entering, at the bottom of the top third of the doorpost. Sometimes it is not clear which side is entrance and which is exit. In such a case a specific question should be asked. The Bracha is "Likboah Mezuza" ברוך אתה ה' אלוקינו מלך העולם אשר קדשנו במצותיו וציוונו לקבוע מזוזה
