Re: [libreoffice-users] Calc SUM Error 502 - How to add results of three IF formulae?

Brian,

Thank you, and sorry for the double post of this message.

The calculation you provided worked perfectly after correctly 
identifying the necessary cells to be used. funny though the same 
formula does not work just 2 columns to the left? See below and I am 
sure identify the cause as I have spent too many hours trying to solve it.

I did not realise that the formula could be simplified that much :|
The extra brackets and 'SUM's were to keep to the BODMAS(Brackets OF 
Division Multiplication Addition Subtraction) maths rule as I did not 
want the greater than sign to only work on a single cell but on the sum 
of a few cells.

The formula worked flawlessly and gave me the same answer when compared 
to a calculator.

HOWEVER,

Needing to use the same scale and rules on a different column gave me an 
incorrect answer?

I have amalgamated the data sheets onto a single sheet so many of the 
cell references are the same, except the cell I need to use as the base.

Using a copy and paste of the formulae below:
The working one:
Cell 
J2=IF(I2>G18,H18,0)+IF(I2-G18>J18,K18,0)+IF(I2-G18-J18>M18,(I2-G18-J18)*L18,0)

The non-working one:
Cell 
H2=IF(G2>G18,H18,0)+IF((G2-G18)>J18,K18,0)+IF((G2-G18-J18)>M18,(G2-G18-J18)*L18,0)

As you can see the block being used has changed from I2 to G2, the rest 
of the formula is much the same, bar the addition of an odd bracket 
pair. The Non-working formula provides the same answer for H2 whether 
the extra bracket pairs are there or not.

FYI:    G2=433 and is manually entered
        I2=1349.31 with formula =SUM(C2,D2)-G2
        C2=1479
        D2=303.31 with formula =O19
        O19=303.31 with formula =SUM(G19:G20,J19:J20, M19:M20)
The answers I seek is for H2.
Using the non-working formula. the only answer I have been able to get 
is R 169.80 (which is =H18). This is incorrect as according to the 
sliding scale the answer should be R 504.05.

What is wrong with the non-working formula as it does not seem to 
continue past the first IF argument?

I have attached the file and hope it will appear on Nabble, as even 
after registering for Nabble, and confirming membership, I saw no 
instructions/options to upload files. Maybe its automatic? Google was as 
usual cryptic.
