Setting a Vaule of Column if one of 2 columns has info

[Drew_Cook]

Here is my code : IF([Agreed Cleaning Fee] < 1, [Cleaning Fee]=[Computed Cleaning Fee], [Cleaning Fee]=[Agreed Cleaning Fee])

My error : The expression is valid but its result type ‘Yes/No’ is not one of the expected types: Price

What I am doing is have a Column showed to the user. I have a Formula that calculates a fee and another column where i can enter a fee. I want it to be if there is a fee enter but that value in the 3rd column and if not put the other data there.
