To fix your code, try -notcontains or at least WRAP your contains-test in parantheses. Atm. your test reads:

If "NOT array"(if array doens't exist) contains word.

This makes no sense. What you want is:

If array does not contain word..

That's written like this:

If (-not ($IncorrectArray -contains $Word))

-notcontains is even better, as @dugas suggested.
