Nested If Formula problem

I need to combine 3 different If Formulas into one, but I can't seem to get it to work for some reason. Here are the three formulas:
=IF(FW80<=CH80,"Adjust to pink","Stay at Forecast")
OR
=IF(FW80="","Zero Forecast","Okay")
OR
=IF(AND(GD80>=CH80,FW80>=GD80),"Change to Open","Stay at Forecast")

One of these situations will happen based on the data that I have in the excel doc.

I'm either getting a value error, or just a general excel formula error.

You can't nest the IF formulas the way you have them written because the IF statements already handle both a TRUE and FALSE condition. Therefore, it will never continue to the other IF statements. In other words, the first IF statement says if it's true, the value should be "Adjust to pink". If it's FALSE, the the value should be "Stay at Forecast". It stops there because there's no reason to go any further.

If, however, your logic was something like, "if FW80 <=CH80, then the value should be "Adjust to pink". If it's NOT <=CH80, then check to see if it's blank. If so, the the value should be "Zero Forecast". If it's not blank, then check to see if GD80>=CH80 AND FW80>=GD80, then the value should be "Change to Open". Then you have to decide on the logic of when none of these is true (do you show "Stay at Forecast", or "Okay").

This is exactly what I needed. Thank you so much
