Table aggregation help (i think)

[samuel_brierley]

Hi all,

first of all thanks for any help with this guys,

as you can see in the table below Equipment M01_0001_3GR_1 fails 7 times with a comms error.

each error has a raised time and a clearance time.

I want to count the faults that occur within 3 days of one another.

in my table I want to have Fault Classification as a dimension and the above calculation as the expression.
