Theres a few different syntax issues here:

  • var = i :point_left: the variable name must follow "var", and come before the equal-sign
  • the value being assigned to the var goes on the right of the equal-sign
  • 4<=i<=156 :point_left: you cannot test a single variable with two operators at the same time
  • but you can combine two individual tests with a logic operator :point_right: 4<=i && i<=156
  • 1=+ i :point_left: a "mirror image" of what you probably intended :point_right: i += 1
