String Functions II, 3/8, continuous error "first strpos should output a number...."?

Hi, I have written out the code exactly as it says in the example, yet it keeps coming up with this error….I write the strpos function, then brackets with my name and a letter from my name with all the correct punctuation, but nothing shows in the window and this error occurs. Its driving me mad!, any help would be greatly appreciated =]
