  • The tags are necessary, but not sufficient.

    The OP did use the tags this time - but it takes more than just tags to make a readable, understandable post.
    the tags only help if as above AND evidently the poster has not heard of indenting. The "code" as is is totally unreadable. I have no idea if other issues may exist, but just seing the lack of indention (which led me to miss the greying since the "code" looks as if it was not "HTMLed"). I do not look at unindented code.

    something else that should be mentioned is that when code is illegible to others it is also illegible to the "coder" this is a proven fact.
