Conditional formatting

[BittenApple]

Hello team,
I have conditional formatting and it is placed on the cells that shows the result of a function.
This works for a sheet but it doesn’t work in another sheet.
If the value of the cell is =0 then format the font white. This works in a tab but I set up same rule in another tab. This doesn’t work on the second tab. Any idea?

Thanks

Are the 0s on the sheet where it doesn't work the result of a formula?

Hello Hans,
Yes, on both tabs, the conditional formatting are place on a result of an array formula.
Thanks

Perhaps the result is not exactly 0. Could you attach a stripped-down copy of the workbook without sensitive info?

It often helps to wrap these formulae in =ROUND(...,2) or similar, to lose any insignificant digits
