In my current query i have to sum three separate sums Bonus: [BonusL1]+[BonusL2]+[BonusL3]. All these fields are calculated fields.However i get no results probably because sometimes only one field is filled in, for example only BonusL3, while the other two are blank.Maybe this is the reason why i get no results.Could you help me ? Also, the sums should be summed up only when the Yes/No field getBonus in the same query is set to Yes.
