broiler element replacement

:o I think I’ve messed up: I was trying to remove broiler element and "lost" one side of the connecting wire. Started when I heard a pop and realized the broiler no longer worked. Bought replacement element, but can’t install, obviously. And now my bake element isn’t heating at all like it should…never got hot after 15 minutes Preheat time. Do I have to call the repairman now?
