In my 2d array, I have ten columns with keys.
To determine which set of keys to print out, I have the link set up to
transer the year and the rank.
$find=$array[$year][$rank]
does nothing.
How do I properly go about retrrieving a particular key value?
With only these paramters to work with?

It assigns the value in $array[$year][$rank] to the variable $find
However, to do so it does require that $year and $rank fall within the
indices of relevant arrays, ie:
That $year is a valid index in $array, and that $rank is a valid index in
$array[$year]

Try dumping $array, $year and $rank, and checking that the above
described requisite conditions are being met.
