I'll try being a bit more explicit, and go line-by-line.

function max(tea, milk){  // good function definition, and your two parameters are "tea" and "milk"
    var tea = 6;          // but don't create a new variable with the same name as a parameter
    var milk = 5;         // same here, neither of these will be needed
    if (6 > 5) {          // use the parameters to represent values, not actual numbers
        return 6;         // return a paramter not an actual number
    }
                          // so if the test failed, return something else here
}

If the hints still don't help, you might find it worthwhile to review the Giving Information to Functions video.

Personally, I wouldn't want to see a "give solution" button.

I think working to resolve issues helps much more to learn that just seeing answers. If you want to see example code, just review the video. And you never need to "wait for a solution", you can always skip a challenge or quiz and continue to the next video.

Now for your challenge code I'll give you some hints:

  • you should never create new variables with the same names as passed-in parameters
  • use the parameters to represent values, don't hard-code values in your function
  • when you return something inside an if code block, you also need to return something else after it

well, I just got it now Thanks, Steven!

function max(a, b){
  if(a > b){
    return a;
  } else{
    return b;
  }
}

 alert(max(6, 5));
