Hi,

I'm using POI HSSF version poi-bin-2.0-RC1-20031102, excel 97/XP

I'm trying to use a nested if formula in excel which is used for writing a 
string based on a cell value. this cell value is also a formula of devision 
("A2/A3"). When I'm using simple IF it works but when I use a nested IF then a 
#VALUE! comes up. When I enter the sheet using excel, go to the cell and just 
press enter on the formula line then I get the proper value. 
What am I doing wrong ?
I have seen that sometimes it does not necessary connected to the fact that the 
devision cell is also a formula but to the fact that the cell is a float and 
not integer and sometimes when I use integer in the IF formula then it works.
Moreover when using % in a formula parser fails.
