## Division by Zero Error

 Author Message bpowers SSCrazy Group: General Forum Members Points: 2967 Visits: 960 Can anyone help me with the following? I am simply trying to add the three fields then divide by the last field. I have added a check for zero, where I want it to simply return Null if the field is zero and not perform the calculations. Any help will be greatly appreciated.`=(iif(Sum(Fields!TotalInvPrimaryPart.Value, "PartNumber")=0,Sum(Fields!TotalInv.Value, "PartNumber")+first(Fields!TotalInvPrim.Value, "PartNumber"),Sum(Fields!TotalInv.Value, "PartNumber"))+iif(Sum(Fields!QTYonOrderPrimaryPart.Value, "PartNumber")=0,Sum(Fields!TotalQTYonOrder.Value, "PartNumber")+first(Fields!QTYonOrderPrim.Value, "PartNumber"),Sum(Fields!TotalQTYonOrder.Value, "PartNumber"))+iif(Sum(Fields!QTYonPMRPrimaryPart.Value, "PartNumber")=0,Sum(Fields!TotalQTYonPMR.Value, "PartNumber")+first(Fields!QTYonPMRPrim.Value, "PartNumber"),Sum(Fields!TotalQTYonPMR.Value, "PartNumber")))/iif(Sum(Fields!AvgMonthDemand12PrimaryPart.Value, "PartNumber")=0,"Null",iif(Sum(Fields!AvgMonthDemand12PrimaryPart.Value, "PartNumber")>0,Sum(Fields!TotalAvgMonthDemand12.Value, "PartNumber")+first(Fields!AvgMonthDemand12Prim.Value, "PartNumber"),Sum(Fields!TotalAvgMonthDemand12.Value, "PartNumber")` bpowers SSCrazy Group: General Forum Members Points: 2967 Visits: 960 I changed up the expression to test for zero at the beginning. The expression looks good and does not reflect any errors, but I still get the #Error in the field when the report is executed.
