Filter dimensional data ased on prompt

[Sep2013]

Hi guys,

I am using leaf members of 3 hirrarchies(Product,brand and market) in the prompt page using the following function:

filter( members ([Profitability Report].[Products] ),
count(1 within set children(currentMember([Profitability Report].[Products]  )  )  ) = 0 )

Now in my report query i need to use product, brand and market chosen on the prompt page to slice or filter my data on crosstab.
How do I use a slicer/context filter to get correct data?

I have tried using a data item similar to prompt query using the following funtion:
Product leaf Memeber=filter( members ([Profitability Report].[Products] ),
count(1 within set children(currentMember([Profitability Report].[Products]  )  )  ) = 0 )

and used this in slicer with formula Product leaf memebers in ?Products?

But when I add another 2 slicers for brand and market, it shows me "-" dashes on the report output
