Report showing data only for current date and not for user defined date

[tarunkrdas2013]

Good Morning Gurus,
We have reports in Cubes and we are building those Cube reports again using  DMR and Database is Netezza, requirement is  whenever user selects Daily,WTD,PTD,YTD,ALL in Report prompt page,i have attached attachment which shows the report output i expect for Daily,WTD,PTD,YTD,ALL.

I have pasted below DMR expression which i used to achieve Daily,WTD,PTD,YTD,ALL.Please suggest why i am unable to achieve the Cube output attached for WTD,PTD,YTD,ALL
also let me know if you can suggest what else expression i could write
