Hi All

Unless I'm doing something really wrong, the calculation of 40*26*30/365 does not come to 85. It comes to 85.48. I've got the data format at 2 decs. For the moment I'm manually typing in this calculation (it does work using a variable prompt but the calc is still the same as if I manually add - in other words, only the whole amount is shown).

Before I throw my laptop - and calculator out of the window, what am I not doing or setting up correctly?
