Sprite Placement By $row / $column

Ok lets see if I can make this understandable. I am trying to setup a gameboard and place pieces and as such I want to place them via a grid. For example here is the code for three pieces as it stands currently. The two // lines were added because [.code] doesn't seem to like empty lines.

// --------------------------------------------------------------------
// Create Musketeers.
// --------------------------------------------------------------------
function CreateMusketeer()
{
	$Musketeer = new fxStaticSprite2D() { scenegraph = t2dSceneGraph; };
	$Musketeer.setPosition("0 0");
	$Musketeer.setSize( "10 10");
	$Musketeer.setImageMap( musketeerImageMap );
	$Musketeer.isSelectable = true;
//
	$Musketeer = new fxStaticSprite2D() { scenegraph = t2dSceneGraph; };
	$Musketeer.setPosition("20 -20");
	$Musketeer.setSize( "10 10");
	$Musketeer.setImageMap( musketeerImageMap );
	$Musketeer.isSelectable = true;
//
	$Musketeer = new fxStaticSprite2D() { scenegraph = t2dSceneGraph; };
	$Musketeer.setPosition("-20 20");
	$Musketeer.setSize( "10 10");
	$Musketeer.setImageMap( musketeerImageMap );
	$Musketeer.isSelectable = true;
}

As you can see the three pieces will share the same properties and as such I want to put the creation into a for loop only changing this line.

$Musketeer.setPosition("20 -20");

What I have attempted is to declare two variables that are $row and $column and then try to use them in place of ("20 -20") above. Now I know the variables are holding the values by way of using the echo command however the code below doesn't seem to work as expected.

$Musketeer.setPosition($row $column);

The sprite is created but instead of being at the intended position it is at the origin.

So anyone have some ideas? It is probably something simple I am overlooking so here's hoping.
