Hi Martin,
to my knowledge the parenthesis work in general, with the exception of passing parenthesis into the d2:condition() function: DHIS2-2813 <https://jira.dhis2.org/browse/DHIS2-2813>

You would be able to write parenthesis in program indicators expressions and filters. What is not supported is nested d2: function calls. 

Please report if you experience problems with parenthesis outside the known issue above.

I wanted to decompose in different indicators, but programIndicators can't use other programIndicators (like the "aggregate" indicators does), correct? Any other way we would apply our proper priorities ?

> Thanks, Lars and Preeti.  I checked the indicator formulation and found a problem with a d2:condition() statement using a text option set value.  I converted it to an integer and was able to see the calculated data across stages.  I think it might be related to the parentheses issue inside the condition as a few other recent emails have suggested.  How should the condition be formulated if you also need to check a text option inside that condition?  Using double quotes on the outside of the formulation does not seem to work properly.  i.e. d2:condition("my_de == '3'", true, false)

I am assuming you want information from two different stages in the same program. Do you have multiple enrollments per person (TEI) in your program? If not I think enrollment indicators will do the job.

When I use an event type indicator, I don't receive any values back because the indicator definition contains data from two stages.

The one change would be that I want to see the weight gain for individual TEIs and view a TEA based on the weight gain amount instead of the average over all tracked entity instances.
