Answer 1

What ways?
Do you know how to access objects in Acrobat JavaScript?
// get TOTAL HPI field object's value as a variable;
var TotalHPI = this.getField("TOTAL HPI").value;
// reset or clear fields that could be adjusted in case they are not adjusted;
this.resetForm(["BRIEFHPI", ]);
// test the value of TotalHPi;
if(TotalHPI >= 3) {
// greater than or equal to 3;
this.getField("BRIEFHPI").value = "X";
if(TotalHPI > 3) {
// greater than  3;
this.getField("EXTHPI").value = "X";
