Dimension Value On expression

[Ayoub]

Hello Community, 

I'm working on project where i can visualise All information in a recapitulated way.

Everything is working like Charme excpet one Dimension, when i'm putting into an expression, it gives 1 as Value.

The Dimension is => damage , and the value which should be displayed in expression  is MNR, But i got 1.

Do you have any ideas about this prob and how i can solve it ? 

Thank you a lot
