Count only Sum of Sales is not equal to 0

[qlik_venu]

Hi,

I have to count the item_Id's only if the Sales is not equal to 0. Also the Sales needs to be summed up to the Item_Ids before the condition : Sales not equal to 0 is checked.

I am trying to use this, but I need the Sales to be Sum( Sales).

Count({$<sales={">0  < 0 "}>} distinct Item_Id)

Thanks,

Venu
