Hi there Gurus!

Just a quick noob problem, could anyone please tell me how I need to imput these array values?

Arrays:
var houseRef = new Array();
houseRef['L1a'] = new Array (250,100,350,700);
houseRef['L1b'] = new Array (600,100,350,700);
houseRef['L1c'] = new Array (950,100,350,700);

Using array values:
Goal:
context.drawImage(img, 250, 100, 350, 700, 0, 0, 200, 400);

This works:
context.drawImage(img, houseRef['L1a'][0],houseRef['L1a'][1],houseRef['L1a'][2],houseRef['L1a'][3], 0, 0, 200, 400);

This doesnt:
context.drawImage(img, houseRef['L1a'], 0, 0, 200, 400);

Thanks for your help in advance!
