Property Calculator, parenthesis doesn't work with operations

Hi,

Parenthesis does not work, because problem is not related to calculation itself, but foreach functionality and how it build string that is counted. Foreach makes rest of the sentence loop for every single "Actividades". Because of that +20 is added for every "Actividades" object, and parenthesis has no effect for that.

There is couple ways to fix this:

1. Set fixed part before the loop:

"20{actividades.foreach()}+..."

2. Add 20 separately:

There can be another rule below this, that will add 20 to end result:

There is also "Next()" placeholder which ends looping in selected point. At least earlier it had some side effects and Property Calculator did not support it. I am not sure what is current situation.

Tanks Jusso, I did tried with another calculation but the server shows a warning when using the same property, I'll try again with your suggestion and let you know how it goes, thanks for your time.

Way number one is not clear to me, just putting 20 before parenthesis adds 20 to the total of related objects?

Way number two why grouping level? I tried this way and looks to be working, is ok for you?

Finally because adding 20 depends on another metadata condition the solucion with your help works this way:

Thanks a lot!

so for general cases is just the sum of all (For Each) and in one case needs to be added 20 to complete the 100%

Your original expression with foreach generates:
"+ {value 1} + {value 2} + {value 3} + ..."
If you add 20 to beginning, you will get:
"20 + {value 1} + ..." which should have wanted impact.

And about grouping level. If you add conditions to grouping level, they are used for both rules. You can be sure that +20 is added every single time the calculation is done. Your solution works as well, but now you need remember to modify both conditions, when any changes are done.
