MDX Report on Date Range

Hi All,

i am doing search through Date Range but didn't get correct result.

For Example if i created a Task on 5/8/2014 and when i have take Date Range from 1/8/2014 to 6/8/2014 then didn't get 5/8/2014 data in result but when i taken range from 1/8/2014 to 5/8/2014 then got the 5th Date data.

 I am taking Range Inclusive Operator(:).

SELECT ( STRTOMEMBER(@FromDate) : STRTOMEMBER(@ToDate) )

I need help ASAP.

Thanks.
