JS if statement wont work

Just using a normal if-statement to check if something is equal or higher/lower than the actual result.

Only getting the else alert..

if(a[22].begin >= b && a[22].end <= b){
    alert("u WON");
  }
  if(a[6].begin >= b && a[6].end <= b){
    alert("u WON");
  }
  if(a[13].begin >= b && a[13].end <= b){
    alert("u WON");
  }
  else {
    alert("Better luck next time");
  }
