Limit to Number of Selections in Multi-Select Text Field

Question

Hello!I have a Multi-select Text field where a user can select multiple options. I'd like to only have the user select up to three options. Is this possible to do through a rule form or something similar? Alternatively, I'd like to put some kind of rule in place where if they select a particular option in the list, it doesn't allow them to select anything else. thanks in advance for any help!

You could make a formula field to count the number of selections and abort the Sav e in a form rule if more that 3.

var text value = ToText([Combined Text Floor ID]);

Count(
Trim(Part($value,1,";"))<>"",
Trim(Part($value,2,";"))<>"",
Trim(Part($value,3,";"))<>"",
Trim(Part($value,4,";"))<>"",
Trim(Part($value,5,";"))<>"",
Trim(Part($value,6,";"))<>"",
Trim(Part($value,7,";"))<>"",
Trim(Part($value,8,";"))<>"",
Trim(Part($value,9,";"))<>"",
Trim(Part($value,10,";"))<>"",
Trim(Part($value,11,";"))<>"",
Trim(Part($value,12,";"))<>"",
Trim(Part($value,13,";"))<>"",
Trim(Part($value,14,";"))<>"",
Trim(Part($value,15,";"))<>"",
Trim(Part($value,16,";"))<>"",
Trim(Part($value,17,";"))<>"",
Trim(Part($value,18,";"))<>"",
Trim(Part($value,19,";"))<>"",
Trim(Part($value,20,";"))<>"",
Trim(Part($value,21,";"))<>"",
Trim(Part($value,22,";"))<>"",
Trim(Part($value,23,";"))<>"",
Trim(Part($value,24,";"))<>"",
Trim(Part($value,25,";"))<>"")
