Formula if for empty values

[Nacho_Gonzalez]

Hi
I have one column called genres 1 and another column called genres 2
I want to add another column that returns me the value of genre 1 when it isn’t blank and returns me the column genre 2 when the column genre 1 is blank
I know I have to use the If function, but I dont know how to apply to this case
Can you provide me some help?
Thanks in advance!

IF( {genres 1}, {genres 1}, {genres 2} )

translation: IF( genre 1 is defined, return genre 1, otherwise return genre 2 )
