#VALUE if cell blank

[The Animal]

Hi
Why do I keep getting a #VALUE Error when I6 is "". It does have a formula in the cell but no actual value

=IF(OR(I6=""),"",(K6+M6)/I6)/24

Thanks for any help
Stephen

You're welcome, no problem at all, sometimes when you stare at your problem long enough, everything becomes "blurry".

Also, I should re-phrase myself, I meant to say you were dividing a "" by 24 or 1440, Not the cell I5 or I6, I misspoke, sorry.
