enter a date onto an Access Form to not accept Wednesdays

[Guest]

Office XP.
I want to enter a date onto a form that will accept it only if it is not a
Wednesday.

I can enter the error message "Not a Wednesday", but I can't find the right
syntax for a formula which refuses Wednesday as a day of the week.
