Single-Select drop down menu autofilling options
I am attempting to select an option from a single-select drop-down that will auto-fill the next column.
I have loaded the formula as a one to one basis, i.e. if 'this person' is selected, populate 'this manager' in the next column. However, I need it to be across multiple employees. So if, this person, this person, or this person is selected, auto-fill this manager. If I attempt to add an 'or' into my formula, I'm getting error messages of UNPARSEABLE or INCORRECT ARGUMENT SET.
Here is my one to one formula:
=IF(HAS(Engineer1, "THIS PERSON"), "THIS MANAGER")
