per diem calculation query

Hi,

With reference to Travel module for Sweden, we have a scenario.

For first 90 days perdiem is 220/day and from 91st day onward the perdiem is 154/day.

I have manintained rules as shown in below screenshots.

System behaviour-

For first 90 days, calculated correctly as 220*90=19800

For 91 days, instead of calculating 19800 (for 90 days) + 154 (for 91st day) it is calculating (91*154) which is not what my requirement is.

URGENT assistance appreciated.

Thx
