Incorrect sum

[Lisa_P]

Works ok for me

[JGMDataAnalysis]

It also gives me 16.

I provide you with a shorter version of the measure...

Sum(
    {<
      [Datum] =, 
      [MeldingBetreft] = {'bijna ongeval, onveilige situatie / handeling'}
    >} 
      [Aantal_open] + [Aantal_gereed]
)

Hi Lisa! thanks for the reply. For privacy reasons, I created a dummy data and mistakenly added 18 of them instead of 16! So I have updated the dummy data and you should now get only 16 as the correct answer. Can you try again for me? Cause I cannot figure out what is wrong.

Thanks so much!<3
