You will have to post the exact code (the simplest case that gives 
trouble)  you are using. Take care to post InputForm - otherwise half 
the characters get trashed by the e-mail process!

Alternatively, start with something that does work - say

Plot[Sin[x],{x,0,10}]

and progressively modify it to do what you want.

Make sure you are using square brackets for all the functions, and that 
you have used the correct syntax for the hypergeometric - the usual 
mathematical semicolon notation definitely will not work!
