How to add count to a dimension field

[Anonymous]

Hello!

I have a treeview with the dimensions Month and Quarter and a measure Holidays.

I want to add next to the Q4 the Count of Holidays.

I want the same thing for December.

It should be like in the image above.

I tried:

= Quarter & Count(Holidays)

but it gives me an Error.

Thanks!

Holidays is Field? or how it is?
