Help with IF AND formula

Hello worldwide Excel community,

I was hoping you could help me tweak a formula I am trying to use.

In Column A I have data with values 1, 0 or (blank), and in column B we have the same values but representing something different. In column C I'd like it to return a "Yes") when Column A is 1 and B is 0.

I have been trying the below but keep getting errors:

=IF((AND(A1=1,B1=0),"Yes"),"No")

Can someone maybe let me know where I am going wrong and offer an alternative?

Any input appreciated!
