Preview calculation in case detail in order to not monitoring objects with 0 value

I created an app for a kiosk distribution and I faced a problem that i want
to share with you in order to advice me what I can do ,
App have 3 modules ,first module is for register a person, second is to
remove or update a person that is already register and the third one is to
monitoring what items each person received from the kiosk.
My problem is in case details . I put all the items in to case details list
In order to monitoring the items each person received . I tried to put a
restriction in to preview calculation in order to not monitoring the items
with “0” value (items that not received from the kiosk to the person).
I did lot of tests with if statement inside the box of the preview
calculation and also I made hidden value inside the form and I placed it
in the box and nothing working . Could you assist / suggest me please

Best regards

As far as I know, Case list only shows properties with value different from
null (ie ‘’). That means, that if there is something in it, may it be '0’
or ’ ’ or ‘nothing’, it all appear the same : it will show in the case list.
The best option is to for the property to ‘’ when there is ‘0’ inside the
form.

Hope it’ll hep !
