Aggregation of last 5 entries

[Florian Beenken]

Morning,

my name is Florian and I am new here. I want to  sum up a field from last 5 entries. Means like a aggregation, but not for the whole database.

Thanks in advance

Florian

Hallo
There is the field Calculations in which one can select several fields and add together with plus.
The whole thing goes with numbers or with string variable.

Thanks. Problem is I want to access fields in other entries(records). In my case last five entries.
