Cyclic group for slider with new expression becomes null when i go up one level

[haribabugv]

Hello Qlik Community,

I have created created cyclic group for dates in the order of Date>Week>Month. I have also created an expression with the condition using variable in the slider.

When i roll it up to week or month , this expression becomes null.

Can you please suggest any changes in that expression?

At day level i can see estimate value on 05-01-2017

at Week level, i am not able to see this value
