Looker Table Calculation - IF statement

[adriana_clinci]

Hi all, 

I m trying to add a table calculation using the If statement. 

I have a column that displays the below

and I want to add an if statement that will show the following: 

IF "Actual" then "No calculations required" , if "EstimatedBasedOnGlobal" then "The global brand results", otherwise "The same market & same brand results"

How can I ass this as a table calculation? 

Thank you!
