Extracting Todays day in a slice

[stayonpointtatt]

Hello,
I am trying to make a slice that only outputs rows that have an datetime of today’s day. Here what I put together

AND(DAY(TODAY()) = DAY([Appointment Date]), [User] = USEREMAIL())

For some reason its not working I’m sure it could be wrongly structured… Please any advice on how I can make this happen!
