You don't seem to have much of a following. 

Do you at least have a question you want help with?

Very Sorry I accidentally posted halfway through the writing. This is my issue

I have following set expression which does not return a value

sum({<VFROM={">=$(v1)"}>}PREMIUM)

VFROM=DEC-2017 (  a field created  while loading data)  Month(POL_PERIOD_FROM)&'-'&Year(POL_PERIOD_FROM)AS VFROM

v1=      =DEC-2017 a vraiable (Let v1=Date(Makedate(2017,12,01),'MMM-YYYY'))

  I seek your help to get my expression corrected

You create your VFROM as a text string value and then use the >= comparison operator to compare that with a date value. I think that's your problem. If you create VFROM as a date value it'll probably work

Date(POL_PERIOD_FROM,'MMM-YYYY')AS VFROM
