Simple Form Rule Will Not Work
First of all to put this in context, I run a golf course and am trying to build a really simple tee sheet that lists the names of golfers signed up to play at a particular time. We encourage people...

If I am understanding your setup correctly, you have 4 separate fields for each golfer, not a child table correct? When creating the record, the count will not exist until the record is saved, preventing the error message from triggering. Instead you can change your rule FROM # of players to <=2 TO: if Golfer 3 is blank. (You may want to add an override button allowing 1 or 2 golfers to sign up...i.e. if override is not checked and Golfer3 is blank)
Golfer1
Golfer2
Golfer3
Golfer4

Okay I did a quick test and this does work in a form rule:
Formula for #ofGolfers
var number golferOne=If([Golfer1]<>"",1,0);
var number golferTwo=If([Golfer2]<>"",1,0);
var number golferThree=If([Golfer3]<>"",1,0);
var number golferFour=If([Golfer4]<>"",1,0);
$GolferOne + $GolferTwo + $GolferThree + $GolferFour

var number golferTwo=If([Golfer2]<>"",1,0);
var number golferThree=If([Golfer3]<>"",1,0);
var number golferFour=If([Golfer4]<>"",1,0);
$GolferOne + $GolferTwo + $GolferThree + $GolferFour

- Hi Christine, thanks so much for taking the time to do this, and sorry for the delay in reply. Here in Ontario Golf Courses just reopened on the weekend after being closed for five weeks due to COVID concerns, so I was too busy with customers to work on my form rule issue
So, in my table I built a new formula field and even named it after you "Christine White Counter", applied your suggested formula (using my field name being counted)
var number golferOne=If(Trim([NameOnTeeSheet1])<>"",1,0);
var number golferTwo=If(Trim([NameOnTeeSheet2])<>"",1,0);
var number golferThree=If(Trim([NameOnTeeSheet3])<>"",1,0);
var number golferFour=If(Trim([NameOnTeeSheet4])<>"",1,0);
$GolferOne + $GolferTwo + $GolferThree + $GolferFour
And it does the counting......
HOWEVER, when I make a form rule
When [Christine White Counter] <3
Action Display a Message "you must book three or four players for online booking"
Still nothing! The form rule never fires?

------------------------------- Form Rules based on Formulas will need to have the initial action be 'When the Record is Saved' in order to fire properly. For your use case, though, the best practice would be to have the first 3 Name fields be set to be Required. Not just on the Form, but in the Field Properties.
In the future, if your policy changes and you no longer want to require a minimum of 3 golfers, you can go back and update the field properties.

------------------------------ - Did you update your form rule to "When the Record is Saved" see Blake's reply?

Christine White
------------------------------- Turns out that using a formula field to trigger a message is the problem......
So, as suggested we simply set up the third field name as a required field (and as most people complete forms in the order they appear on the screen, until someone realizes that field is the golden ticket, it should work).
I guess I should mark the problem as solved, plus I learned something.
Thanks all.
