Expression in a Calculated Member

Hi everyone

I have a calculated member in my cube where I perform my necessary calculations but I am unable to check these calculations (in the cube browser) based on my time dimension When I browse the cube and add the time dimension in the Filters fields area (after draging all other necessary measures, calc member & dims to each area), the calculations (data) only work for one particular dayid (when i select one dayid from filters area).
Can anyone plz suggest/help me on adding the slicer expression (mdx) for time dimension. Help will be really appreciated.

Thanks,
