How do I make one if statement run after the other has run and the button is clicked again?

I’ve tried making if statements that activate other if statements but they just ran them both at the same time. I also tried else if statements but that didn’t seem to want to work… So how would I make an if statement that activates once the past if statement has been run and the button is pressed again. I hope that makes any sense in y’alls head. The help would be appreciated. 🙂

let One = true
let Two = false
let Three = false
function right() {
if(One === true){
if(Two === false){
document.getElementById("2").innerHTML = 1
 document.getElementById("1").innerHTML = ''
 Two = true
  One = false
  } else {
  if (Three === false) {
   document.getElementById("3").innerHTML = 1
   document.getElementById("2").innerHTML = ''
  Three = true
   Two = false
    }}}}
