[libreoffice-users] Calc Function Wizard - IF Result differences

Hi,

Entering a formula into the Function Wizard in Calc shows  up two 
different answers in the 'Result' and 'Function Result' answer box.

If the editing cursor is placed in a certain section of the formula, 
only the 'Function Result' answer box holds the correct answer i.e. 
751.52004. Pressing 'OK' puts the 'Result' answer box value in the 
calculated cell, which unfortunately is the wrong answer i.e. 751.25.

I have looked at the help file to see if there was a difference between 
the Result answer boxes but found none.

The initial formula is:
=IF(0<G4<=$G$20,G4*$F$20,IF($G$20<G4<=$J$20,(G4-$G$20)*$I$20+($F$20*$G$20),IF($J$20<G4<=$M$20,(G4-$G$20-$J$20)*$L$20+(($G$20*$F$20)+($J$20*$I$20),IF($M$20<G4<=$P$20,(G4-$G$20-$J$20-$M$20)*$O$20+(($G$20*$F$20)+($J$20*$I$20)+($M$20*$L$20),IF(G4>$P$20,((G4-$G$20-$J$20-$M$20-$P$20)*$O$20+(($G$20*$F$20)+($J$20*$I$20)+($M$20*$L$20)+($O$20*$P$20))))))))))

In addition I have tried changing the formula without success to try and 
reduce the multiple nested IF functions:

i.e.:
=sum((IF(0<G4<=$G$20,G4*$F$20,0),(IF($G$20<G4<=$J$20,(G4-$G$20)*$I$20+($F$20*$G$20),0),(IF($J$20<G4<=$M$20,(G4-$G$20-$J$20)*$L$20+(($G$20*$F$20)+($J$20*$I$20),0),(IF($M$20<G4<=$P$20,(G4-$G$20-$J$20-$M$20)*$O$20+(($G$20*$F$20)+($J$20*$I$20)+($M$20*$L$20),0),(IF(G4>$P$20,((G4-$G$20-$J$20-$M$20-$P$20)*$O$20+(($G$20*$F$20)+($J$20*$I$20)+($M$20*$L$20)+($O$20*$P$20)),0)

The SUMIF function was also tried but my brain just gave up.

I cannot see how the VLOOKUP function will help either as I am not 
looking up values from cells, I am calculating a single value in H4 
based in a variable input in G4.

Have a peak at the uploaded spreadsheet on Nabble:

http://nabble.documentfoundation.org/file/n4077843/Electricity.ods

You will see that provided you enter a value for G4 below 600 the 
correct answer is shown i.e. for 600 in G4 H4=750. The moment G4 exceeds 
600, even by 1, there is a problem.

There must be an answer and or  my formula syntax is wrong unbeknown to me.

Help would be very much appreciated

Sincerely
Hylton
