how do you organise your code so you can re-use things?

thank you both for your help.

being able to abstract the presentation is exactly the missing piece I couldn't work out.

I had sort of solved the problem by using multiple views that were composited together, the it was so cumbersome and complex it didn't seem worth the effort for the greater theoretical 'flexibility'

modules though look like they will allows me to do exactly what i have been hoping to do.

thanks
