Calculate Sum of List Elemets

[sebastian]

I'm having trouble calculating the totals in the grid box. What I mean by that it I have to click back and reload the page for all my totals to correctly add up whenever I add newly added food. Any suggestion?

Hi Sebastian,

Not sure i understand you correctly.

But if you need just "udpate" list and numbers - you should just invoke datasource that's populate your grid.

You can do it with two general ways:
1 With event linking (action - "Invoke service").
2 With JS code:

pre

//Note: you should replace "dataSourceName" with your datasource name.
service.dataSourceName.execute({});

/pre

Regards.
