=>Here's my code......

\usetikzlibrary{shapes,geometric,arrows}

\tikzstyle{arrow}=[thick,->,>=stealth]
\begin{document}

It should be shapes.geometric, not shapes,geometric. Period, not comma.

You could also say just shapes, which I think loads all the various shape libraries.

Some other comments about your diagram:

  • You need \usepackage[T1]{fontenc} for the < to be rendered correctly.

  • You've called the first node Start, but the next node is placed relative to start, so that throws an error. Node names are case sensitive.

  • The <position> of=<othernode> syntax you've used is actually deprecated, it is recommended to load the positioning library, and use <position>=of <othernode> instead. See Difference between "right of=" and "right=of" in PGF/TikZ

    If you want the node distances to be calculated between the centre points of nodes, add the on grid option to the node settings.

  • It is also generally recommended to use 

    \tikzstyle{<stylename>/.style={<settings>}}

    instead of

    \tikzstyle{<stylename>}=[<settings>]

    See Should \tikzset or \tikzstyle be used to define TikZ styles? for some discussion.

  • An alternative to having xshift/yshift in addition to e.g. below=of .. is to write e.g.

    below left=1cm and 3cm of someothernode

    The first value (1cm) is the vertical distance, and the second (3cm) is horizontal distance.

  • Your diagram is far too wide for a standard page, so you'll need to compress it. For example by reducing the space between nodes, reducing text widths, and reducing font size. I did all of that here, and as it is now the diagram fits within the margins of a standard article page.

    It doesn't look like you're entirely done though, so you might have to tweak things more.
