Simple Form Rule Will Not Work

Question

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 to sign up as threesomes or foursomes.

I have a pre-made table, that includes a record for each tee time for the day. To make it simple, lets say that table has six fields, time, one field for the name of each golfer in the foursome and a formula field "total number of players" that counts the number of golfers in that record. (and the counter works).

As we want to encourage golfers to sign up as a threesome or a foursome, I want a very simple form rule that fires a message if the number of players in the record is less than three.

So, I have a form rule that says if "total number of players"<=" 2 "display the message" you must book a minimum of three players

When I modify a record and only enter one or two names, the counter shows "1" or "2" but when I hit save, no message is displayed?

It seems simple to me, but I have been fighting with this all afternoon.....

It might be easier to just require 3 of the 4 Name fields.

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

If you haven't already, try making the form rule:

When the record is saved and # of golfers is <=2, display message.

I don't think the display message fires simply from a formula field changing.

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?
