I have multiple required fields on a single card.

I use this formula, but it's still submitting the form.
If( IsBlank(DTRLoc.Selected.Result) && IsBlank(RadioTimeInOut.Selected.Value) && IsBlank(RecordTimeLoc.Text), Notify(" Missing Info. Check your Time Details"),
) ;
What I am trying to do, is if one or more fields is blank, display notification. Else if all is not blank, submit the form.
