What is wrong with my equation? or set analysis?

[#1]

I need to get a nuber of days between two dates and compare it if it greater than 0 and less or equal to 7.

So, I have come up with the equation below, but it said "error in set modifier expression."

what is wrong with that?

Count({<Num(SERVICE_ACT_TERM_DATE-SERVICE_DATE_START)={">0<=7"}>}PERSONID)
