Ok, I had just been translating everything as directly as possible, so if it ws genitive "'s or of" , dat "to/for" etc. I just started in the last two lessons to drop the to/for with datives, realizing that it is often not nessecary in English. I guess I really need to break free with all the prepositions. I don't think I realized that. So, thanks so mush for the hint it is really a good thing to know.
thanks for your continued help
