Where are you. What type frame and what type foundation are you running. What part of the frame is broken. Being new you probably don't have spare parts, but most of the frame parts aren't hard to make. Does it have brood in the frame or honey. You may leave it alone, replace the part of the frame that is broken, cut out the comb and put it in another frame or try to repair the frame without removing the broke piece with a splint for now. Good luck to you and your bees.
