    ! Undefined control sequence. \subitem is what i get with your code. – Johannes_B Feb 4 '18 at 13:55

    Indeed: where do you get \subitem from? You probably want a nested list ... – Joseph Wright Feb 4 '18 at 13:55
  • Add \newcommand{\subitem}[1]{#1}. If the error vanishes, your editor is not helpful for you. – Johannes_B Feb 4 '18 at 13:56
  • @Johannes_B Now i get this error after deleting \subitem File ended while scanning use of \beamer@collect@@body – medboy94 Feb 4 '18 at 14:01
  • @medboy94: You use a subsection without having a section command before. That might cause problems. – leandriis Feb 4 '18 at 14:06

As various comments already stated: To create subitems in beamer, simply nest the itemize environments.


A few other remarks:

  • instead of \usepackage{beamerthemeWarsaw} use \usetheme{Warsaw} (this is the more beamerish way to load a theme)
  • you don't need \useoutertheme{shadow}, this is already included in the Warsaw theme
  • with \begin{itemize}[<+->] you don't need to manually put a \pause after each item.
