Hi - it's James again with his Calc cashbook and another challenge ...
I have used array functions to add up all the debits and credits for
differing categories, eg:
my code, in Column A, for vehicle expenses is "v" and if I want to know how
much I spent on vehicles in the financial year ending 30/6/07, this formula
will answer my query:
{=SUM((E7:E2000)*(A7:NAB.A2000="v")*(B7:B2000>=D4)*(B7:B2000<=D5))}
where D4 is the start date, 1/JULY/06 in this case, and
where D5 is the end date, or 30/JUNE/07, and
where E is the debits column (expenditure), and
where B is the Date column
In pseudocode: if(code=i) and if(D4<=Date<=D5) then SUM(Column E)
The actual formula I use is complicated by the addition of Sheet-names and
generous usage of the $ symbol to make all references Absolute (as distinct
from Relative), so the formula does not change when copied from cell to
cell, and I think I might have made a typos because it did not work properly
when tested.
In the end, I selected all the cells and hit Delete, and they all went
blank, as one would expect.
Now, when I try to enter anything into the cell I get a pop-up error message
saying:
"You cannot change only part of an array"
If I select a cell the array formula is still there, but if I try to delete
it, I get:
"You cannot change only part of an array"
and if I try and edit it (or delete it) in the formula bar, I get:
"You cannot change only part of an array"
So, I am sorta stuck ... I cannot delete my formulas and cannot proceed
until I do.
Any advice or suggestion would-be most welcome.
James
