Hiya,

The code I posted was a rough, un-run, first draft typed straight into
the email client, but even so, I did a little re-arrangement and
DRYing while composing, and left an extraneous "if" on the first line
of win_lose_tie. This is what it should look like (the if condition at
the end of the line is a modifier, or "guard" - not a construct that
PHP supports AFAIK ;-)

def win_lose_tie
return :tie if schedule.for.to_i == schedule.against.to_i
schedule.for.to_i > schedule.against.to_i ? :win : :lose
end

Bear in mind that I haven't run it - so it may need a little
debugging. The intention of my post is that you see more clearly the
direction the code should be heading towards (rather than having huge
logical constructs in your views).

To be honest, I don't really see how "trying in PHP" is going to go
any way to solving a problem you have in Ruby - it's certainly not one
of the first debugging steps I would recommend :-/
