if condition output in a different cell

[thunderspeed]

Hi guys ,
Please , I need help with the following :
I want to make an if condition
=IF(OR(BB4-BC4>0.001 , BB4-BC4<-0.001),BC4=BG4 ,BF4=BD4) , its not working
the idea is that I want to change values of other cells as well using the if condition , how can i do so ?
thanks in advance

you can't change value of other cell with the formula, you need to use VBA for this
