Formula outcome missing if no value to calculate

[#1]

Hallo,

I'm having a problem with a balance sheet.

The balance is designed in this Structure: Open, Expenses, Income, Close

Each of this 4 fields is calculated for every day and the formulas are related to each other in the following way:

Open = If(Date>Date(Today()-1),sum({$<Day={$(=Day(Today()-1))},

                         Month={$(=Month(Today()-1))},

                    Year={$(=Year(Today()-1))}>}

                         TOTAL<CompanyDesc,BankName,AccountName> CloseAmtCurr)

                         + rangesum(Before(Sum({<TranType={'TranName'}>} TranAmtCurr),1,Columnno()))

                    + rangesum(Before(Sum({<TranType={'TranName2'}>} TranAmtCurr),1,Columnno())),

             if(Date=Date(Today()-1),Sum(CloseAmtCurr)))

Expenses=if(Date>=Today()-1,Sum ({$<TranType={'TranName'}>}TranAmtCurr))

Income=if(Date>=Today()-1,Sum ({$<TranType={'TranName2'}>}TranAmtCurr))

Close = if(Date>=Today()-1,[Open]+[Income]-[Expenses])

My problem is that when i have a date that does'nt incloud Expenses and Income the formula also omit the value of the Open and Close.

I want the open and close to be presented allways.

The logic of the Open and close should be like this:

(Today) Open = (Today-1) Close

(Today) Close = (Today) (Open + Income - Expenses)

I would Thank for any suggestion.

Thanks,

Uri
