:point_right: Here's a few observations:

  • the variables "red" and "blue" are passed to the function, you don't want to declare or assign them
  • you have a "return" before you have tested anything
  • you return "answer" which was never declared or assigned
  • your function ends (at the closing brace) before getting to your "if" statement
  • the "if" would be good if it was inside the function
  • inside the if you assign "answer" but you could just "return blue"
  • you still need to return the other value when the if test is not true

You might want to revisit the videos about function structure and passing arguments and returning values.

I will see what I can do with what you said. I have rewatched those videos already and still having the same problems. I am more of a visual learner and lots of words don't help me too much.

I found some place else that gave me a better answer. I used the if and else to return what I needed and got rid of the vars.

Just so those checking this post later here is a formatted answer

function max(red, blue){
  if(red > blue){
    return red;
  }else{
    return blue;
  }
}
