I have setup a IF OR function, but I need to put a third option on there and I am having trouble.

What I have currently. **A**
=IF(OR(D17=AB6,D17=AB7), "Target Change: ", "Current Target: ")

What I want to add (RED UNCERTAINTY) ***B***
=IF(OR(D17=AB6,D17=AB7,D17=AB8,) "Target Change: ", "Current Target: ", Suggested Target: ",)

The function works in **A**, but I am unsure how to get ***B*** to work & demonstrate what I would like to see.

Thanks for your help.
