Is there another way to express the line: ('sTOC'+number).style.display = "none"; ??? i keep getting an error: 'style' is null or not an object

function figEnable(choice, number)
    {
    	if(choice == "No")
    	{
    		('sTOC'+number).style.display = "none";
    		("sQty"+number).style.display = "none";
    		("sRate"+number).style.display = "none";
    		("scalcTotalCost"+number).style.display = "none";
    	}
    	else
    	{
    		('sTOC'+number).style.display = "";
    		("sQty"+number).style.display = "";
    		("sRate"+number).style.display = "";
    		("scalcTotalCost"+number).style.display = "";
    	}
    }
