Hiya,
I have the following code ... which only seems to result in one item ...
which is incorrect ... can anyone spot my problem?
if ($armbase != "") {

$get_columns = 8;
$get_hloopRow1 = 0;

$text .= '</tr>';
$get_endRow = 0;
}
} while(list($key,$value) = each($options));
The first time around the loop, both $key and $value are undefined, as
you're not setting them until the end condition.
But that's not a big deal as nothing gets done first time through the
loop except for $get_hloopRow1 getting incremented.
The next time through the loop, because $get_hloopRow1 is now not
zero, the first conditional gets executed. You add some html and the
first value from the array to $text to the string and incremenent
$get_endRow.
All subsequent times through the loop, nothing gets done because the
$get_endRow == 0 condition fails. $get_endRow never gets incrememented
again.
that help at all?
