Not familar with the flash product, sorry . . . but a couple small(ish) things I don't grok.

$lat = $row['lat'];
$long = $row['long'];

OK . . so you have scalar values for $lat and $long. Not arrays (lists,) but single values. Then you do

$n = count($lat);

which (should?) always give you a 1 . . or maybe even a warning/error since it's not an array, nothing to count. Then where you really lose me is

$ymax = $lat[1];
$ymin = $lat[1];
$xmax = $long[1];
$xmin = $long[1];

Which indicates, to me, you have either previously defined the array $lat and $long - which you just killed and re-set as a scalar above - and are setting your x/y's to the second member in these arrays. Which don't exist. For example

$lat = new Array();
$lat[1] = 'some_value';

Since there's no zero'th (first) member, the array $lat is now

[null,'some value']

So my point is, from the code you have there, all four of your x/y values . . . should be null.

Deal's off for me at that point, I don't get it. :-) But further on, echo $n gives you a 1, right? OR is it null? (Never tried to count a scalar.)

for ($i=0; $i<$n; $i++)

So this should go through once. 0 < 1 is true. But there's no member at $long[0] or $lat[0].

The final point of "where am I, what am I doing" is this.

$track[$i] = new point ($long[$i], $lat[$i] , 3);

This indicates you have to have some class with a function or constructor for "point." I looked, no PHP function "point."

Maybe more info is required, dass' all I got.
