Extjs 4.2: get value from the grid

So let's say I have this grid

id time

1 10

2 5

3 10

etc..

How do I get the sum of the values under 'time'?

EDIT

I tried to get the array of the value from the grid with this code

var sel2 = scope.getPlaylistDetailsGrid().data.items;

But it says: Uncaught TypeError: Cannot read property 'items' of undefined

You could use summary row, to achieve this behaviour. Here is example

If you want to display the sum in the grid, then Riku's suggestion of the summary row is perfect. If you need to just get a sum in code, you can check out the store's sum() method: http://docs.sencha.com/extjs/4.2.2/#!/api/Ext.data.Store-method-sum
