Slices

Hi, All

I have 2 tables: Orders and Customers
How to make a slice from Customers ( I suppose) who made Orders this month (or this week, never mind) so I can make some actions with them (bill them, send them email)

There is no problem with time frame, but with the selection of Customers

Thanks beforehand

Sorry, found solution by myself
But the situation was very stupid

Slice formula looks something like this
IsBlank([Related Orders])=False

But I could not see results because of some bug
When I tried “View Data” I saw only head of table with empty screen

To see results I should scroll it down
