Include fejl

Hej, håber I kan hjælpe mig. Jeg er ved at prøve at lave en side med 3 frames, ved hjælp af include, så det virker som her på eksperten ved at de scroller med ned af... Anyway, når jeg loader nedenstående side første gang så virker det fint. Der kommer en top bar, en menu i venstre side og en side med info midt i det hele. Når jeg så prøver at bruge min menu i venstre side for at få vist noget andet i main vinduet, så skifter den alt indhold ud! Hvad er fejlen i min kode!
