getselectedcount not working for all fields?

[Anonymous]

Hi,

I have a question regarding the getselectedcount function.

I am using it in a diagram exactly like in der handbook:

getselectedcount ( Jahr )

But for some reason it is not working with the Field "Jahr" it always is null. With other some other fields in the same .qvw it is working fine.

Is there any constraint that only particular fields can be used in getselectedcount?

Regards,

Matt
