How to refer to Field Name with a ? in it in MS Access VBA code

Simple question, but I am new to databases. I have a field called 'ActorRetired?', and in some VBA code I need to set the value of it to -1. But When I try:

Me.ActorRetired?.Value = -1

I get the error 'Compile Error: Expected: Expression' with the question mark highlighted. How do I refer to the field name without this error? So far I have tried

Me.[ActorRetired?].Value = -1
Me."ActorRetired?".Value = -1

But neither has worked. Please help!
