Unsupported operand types

I keep getting this error:
Fatal error: Unsupported operand types in
/usr/local/etc/httpd/htdocs/djtricities/kat/bpmchart/chart.p hp on line
58

I've looked for hours for some type of error, and tried lots of
different things, but I can't get it to work. I did a google search
for "unsupported operand types" and for most of the people getting this
error, it was something to do with the version of PHP that they were
running, but I can't change that because it's a shared server from a
hosting company. I'm using PHP version 4.3.11 on Linux. Heres the
program around line 58:
_________________________________
function makeTable($myarray){
$result = "";
for($row = 0; $row < count($myarray); $row++){
$result .= '';
for($col = 0; $col < count($myarray[$row]); $col++){
$result .= '' . $myarray[$row][$column] . '';
}
$result .= '';
}
return $result;
}

function bpm($cue, $play){
//if( abs($play - 2 * $cue) < abs($play - $cue) ) $cue = $cue * 2;
//else if( abs(2*$play - $cue) < abs($play -$cue) ) $play = $play *
2;
return ((-100 * ($cue - $play))/$cue); // ***LINE 58***
}
?>

What's actually in $cue and $play? Try echoing them to see. I suspect
one or both is not numeric.

Re: Unsupported operand types

shouldn't this
$result .= '' . $myarray[$row][$column] . '';
be
$result .= '' . $myarray[$row][$col] . '';

and I assume $cue is not zero
and then both $cue and $play are numerics

what's the code that calls this bpm() function look like ?

Re: Unsupported operand types

Thanks, you were right, I was passing the bpm() function arrays. But I
still can't figure out how they got to be arrays. I used the each()
function in a while loop. Heres the code that calls the function:
while($col = each($cols)){
$rowNum = 0;
while($row = each($rows)){
$result[$rowNum][$colNum] = bpm($row, $col); //$row and $col are both
arrays here for some reason...
echo $result[$rowNum][$colNum] . '-';
$rowNum++;
}
$colNum++;
}
echo '

Yeah, http://php.net/each or try http://php.net/foreach
