I am using Allen Brown's recurring events database that I found from his page on the internet. I have modified this just a little bit and was wondering about the IIf statement written below. This statement returns a "date" each time the event occurs. I want to have a parameter between [Start Date] and [End Date] so I can pull events for a specified date range. I have tried this "«Expr» [EventDate]" Between [start date] And [end date] but it returns "null" results. I
have tried everything I know how to do, which I can say is not much because I am in the learning stages of Access. I am using access 2010
EventDate: IIf([tblEventException].[EventID] Is Null,IIf(([qryEventCartesian].[PeriodTypeID] Is Null) Or ([qryEventCartesian].[PeriodFreq] Is Null) Or ([qryEventCartesian].[InstanceID] Is Null),[qryEventCartesian].[EventStart],DateAdd([qryEventCartesian].[PeriodTypeID],[qryEventCartesian].[InstanceID]*[qryEventCartesian].[PeriodFreq],[qryEventCartesian].[EventStart])),IIf([tblEventException].[IsCanned],Null,[tblEventException].[InstanceDate]))

EventDate: IIf([tblEventException].[EventID] Is Null,IIf(([qryEventCartesian].[PeriodTypeID] Is Null) Or ([qryEventCartesian].[PeriodFreq] Is Null) Or ([qryEventCartesian].[InstanceID] Is Null),[qryEventCartesian].[EventStart],DateAdd([qryEventCartesian].[PeriodTypeID],[qryEventCartesian].[InstanceID]*[qryEventCartesian].[PeriodFreq],[qryEventCartesian].[EventStart])),IIf([tblEventException].[IsCanned],Null,[tblEventException].[InstanceDate]))
