Excel 2007 : In need of a formula to check values are even or odd based on other cell

Morning,

Suffering the flu so the brain cells are not performing at peak efficiency. (not that they ever do)

Anyway, Could someone come up with a formula for the following.

Need to check if the value in E21 is >= 3000

if it is then if the value in N19 is between 0 and 179

the value of the thousands(3000, 5000,7000,etc) in E21 must be odd.

if N19 is between 180 and 359, then E21 must be even(2000,4000,6000,etc).

I hope that makes sense.

Right now I can't believe anything that I think!

Thanks in advance.

George
