Set analysis issue

[risabhroy_03]

I am using this 

Sum({<[Ship_Date_GMT_Updated]={"$(vLastmonthdate)"}>} Quantity)

but now I also want to modify my condition where [Ship_Date_GMT_Updated]<={"$(vLastmonthdate)"}

I did this but it came as '-'

Try this:

Sum({<[Ship_Date_GMT_Updated]={"<=$(vLastmonthdate)"}>} Quantity)
