Sum of values in a form
Folks,
I have read numerous threads on this topic, and understand that in order for my Sum() to work I need to ensure all references are made back to the Record Source. I have endeavoured to do this, but am still getting #Error. I am trying to Sum the revenue each tenant provides in a given date range, to give a total revenue figure. If the date range is a whole month, then the expression just takes the value of Rent PCM, and not (Rent PCM*(12/52)) * No. of Days, which would give some unusual results. My Expression looks like this: =Sum(Nz(IIf([Short Let]=-1,[Rent pcm],IIf(Day([Forms]![Revenue Report]![Start Date Chosen])=1 And (Day([Forms]![Revenue Report]![End Date Chosen])=Day (DateSerial(Year([Forms]![Revenue Report]![Start Date Chosen]),Month([Forms]! [Revenue Report]![Start Date Chosen])+1,0))) And (Month([Forms]![Revenue Report]![Start Date Chosen])=Month([Forms]![Revenue Report]![End Date Chosen] )) And (Year([Forms]![Revenue Report]![Start Date Chosen])=Year([Forms]! [Revenue Report]![End Date Chosen]))=-1 And [Moved In]=[Forms]![Revenue Report]![Start Date Chosen] And ([Moved Out]=[Forms]![Revenue Report]![End Date Chosen] Or [Moved Out] Is Null),[Rent pcm],DateDiff("d",IIf([Moved In]= [Forms]![Revenue Report]![Start Date Chosen],[Forms]![Revenue Report]![Start Date Chosen],[Moved In]),IIf([Forms]![Revenue Report]![End Date Chosen]= [Moved Out] And [Moved Out]=[Forms]![Revenue Report]![Start Date Chosen], [Moved Out],[Forms]![Revenue Report]![End Date Chosen]))*([Rent pcm]*(12/365) ))))) I wonder whether referencing back to another form where I have entered the dates for the query range (Start Date Chosen and End Date Chosen) are the current cause of my problem. Any thoughts gratetfully received. Kind Regards, Russell. -- Message posted via AccessMonster.com http://www.accessmonster.com/Uwe/For...forms/200911/1 |
