	// Tip from the blog post: http://ldunham.blogspot.ca/2012/01/melpython-adding-number-padding.html

	int $lengthNum=size(string($num));
	string $padString;

	if($lengthNum<$padding){
	for($i=0;$i<($padding-$lengthNum);$i++){
	$padString=$padString+"0";

	if string.find(fusion:MapPath("Fusion:\\"), "Program Files", 1) then
	-- Check if the OS is Windows by searching for the Program Files folder
	platform = "Windows"
	elseif string.find(fusion:MapPath("Fusion:\\"), "PROGRA~1", 1) then
	-- Check if the OS is Windows by searching for the Program Files folder

	int $paneChildren = `paneLayout -query -numberOfChildren $pointedPaneElement`;
	string $docTag = `paneLayout -query -docTag $pointedPaneElement`;
	int $visible = `paneLayout -query -visible $pointedPaneElement`;
	int $manage = `paneLayout -query -manage $pointedPaneElement`;
	int $enable = `paneLayout -query -enable $pointedPaneElement`;
	int $width = `paneLayout -query -width $pointedPaneElement`;
	int $height = `paneLayout -query -height $pointedPaneElement`;

	-- Find out the current operating system platform. The platform local variable should be set to either "Windows", "Mac", or "Linux".
	local platform = ""
	if string.find(fusion:MapPath("Fusion:\\"), "Program Files", 1) then
