Why doesn't working with array's ever stick in my thick head?

Hi Everyone,

SO it's friday, I'm tired, and I can't seem to think straight... I am  
attempting to do some very basic math with some arrays... Here's the  
pseudo code that I'm working with:

NumberOfPieces * PieceWeight = TotalWeight

explode total weight to get tenth's of pounds, then divide tenth's of  
pounds by 16 to grab ounces.

Display TotalWeight # Exploded Ounces.

Which I have working just fine for a single set of boxes...

My problem is I want to be able to automatically add say 50 boxes in a  
form to process the weight of each route...

So what I need to do is probably use some kind of a counter to loop  
through my $RoutePieces array and multiply by the $PieceWeight?  
$PieceWeight is a static number.

Now let me show you some abbreviated code to try and explain what I'm  
using right now:
<?PHP
	$i= "0";
	$num= "2";
	$PieceWeight = $_POST['txtPieceWeight'];
	$RoutePieces[] = $_POST['txtRoutePieces'];
	$RouteNumber[] = $_POST['txtRoute'];
	
	$totalWeight = $PieceWeight * $RoutePieces/16;
	$weightExplode = explode('.', $totalWeight);
	//$weightOunces = ((float)('.' . $weightExplode[1])) * 16;
	// Use stut's method... Seems cleaner
	$explodeOunces = ($totalWeight - intval($totalWeight)) * 16;

		while($i <= $num){
	echo <<<HTML

		<p>
	Route Number:<input type="text" name="txtRoute[$i]" size="4" value  
="{$RouteNumber[$i]}"> Number of pieces: <input type="text"  
name="txtRoutePieces[$i]" size="4"  
value="{$RoutePieces[$i]}"><label>Total weight of route:  
{$weightExplode[0]} # {$explodeOunces} Ounces</label>
	</p>

		
HTML;
			
	$i++;
	echo $i;
		}
?>

the $_POST array has the proper values stored properly... I just can't  
seem to figure out how to work with the values... Any ideas? Or slaps  
on the back of the head to wake me up a little? :)

I need help :P
