Hi there Stanley and Emma,
sorry for the delay.

For Emmas Question - To count wether someone has received services or not - but avoid counting them twice - you can make the following indicator:
Analytic type: Event
Aggregation operator: Count
Expression: V{tei_count}
Filter: V{program_stage_uid} == 'THE UID OF YOUR SERVICE PROGRAM STAGE'
(if you are using 2.25 or older, the last filter is not possible - you would have to make a filter checking one of the mandatory data elements in your program stage(s) used for giving services)

For the original two issues from Stanley:
The interval between two events of the same stage is not currently possible to calculate with the current program indicator functionality. We hope to make full support for this in a coming release. To work around this in the current solution, you would have to register the interval since the last event as a data element in the repeating program stage. This data element could be something that the data entry user calculates and enters, or it could be auto assigned by a program rule. The vulnerability with using a helper data element would be the fact that the interval is a part of the data, and if you already have data entered these older events would not have the correct value in this data element. If you change your mind or there is an error in the data, it would be manual work to go through and rectify them.

Finding all patients that is negative and with more than 120 days since the last service can be done in 2.26 and later with the following program indicator:
Analytic type: Enrollment
Aggreagation operator: Count
Expression: V{tei_count}
Filter: #{DATA ELEMENT FOR DIAGNOSIS} == 'Negative' and d2:daysBetween(V{event_date}, V{current_date}) > 120

Hope this helps.

Best regards
Markus
