how to crate a calculated column based on time between hours (08:00-18:00)

[TomBrown]

hello 

im trying to crate a column that has a value of "working hours" or "out of the office hours" 

and this would be by the value of a [opend time] , if the time in the opend time column is btween 8:00-18:00 then i wolud like to set the value of the new column to "working hours"

and if it not in those hours then it should say not working hours.

iv tried using an if statment and im getting an error 

Expression.Error: The name 'IF' wasn't recognized. Make sure it's spelled correctly.
