Tell a GuiSrpiteControl who's his parent

I just want to tell the GuiSpriteControl below that %guiParentControl is his parent, right now the sprites are filling the whole screen, i'm not using taml becuase the ammount of spriteCtrl i'm creating is unknown at compile time, i'm trying to create a health system similar to The legend of Zelda.

function createHP(%amount)
{
	%posX=10;
	%posY=10;
	%guiParentControl = new GuiControl()  
	{
		Name="BackgroundMenu"  ;
		canSaveDynamicFields="0"  ;
		isContainer="1"  ;
		Profile="GuiDefaultProfile"  ;
		HorizSizing="right"  ;
		VertSizing="bottom"  ;
		Position="0 0"  ;
		Extent="1024 768"  ;
		MinExtent="8 2"  ;
		canSave="1"  ;
		Visible="1"  ;
		Active="1"  ;
		hovertime="1000"  ;
	};
    
	Canvas.pushDialog(%guiParentControl);
	//echo(%guiControl.getparent());
	
	for(%i=0;%i<%amount;%i++)
	{
		%hpCrystal= new GuiSpriteCtrl()
		{
			Name="genericLifeCrystal"  ;
			canSaveDynamicFields="0"  ;
			isContainer="0"  ;
			Profile="GuiDefaultProfile";  
			HorizSizing="relative"  ;
			VertSizing="relative"  ;
			Position=%i*%posX SPC %posY ;
			Extent="10 10";  
			MinExtent="8 2"  ;
			canSave="1"  ;
			Visible="1"  ;
			Active="1"  ;
			hovertime="1000";  
			Image="mainModule:gems";
			setImageFrame=2;
		};		
		
		Canvas.pushDialog(%hpCrystal);
	}
	//echo(%hpCrystal.getparent());
	
}
