You have to go to the bottom. Usually there are dots a the end of the formula. Put you r cursor between any of the dots. I insert each name, skip a dot and insert another name. Make sure you the inserts are after the complete formula. Some times there is character right at the end, you have to make a bunch of dots after it. If you have problems just note me.
