It looks like Task 1 is no longer passing. I have no idea what I should put in the function.

I put like this in task one: function (str){ return str; }

And second task, I put 'My argument' in parameter but I have no idea what I should do next. Please give me advice.

Thanks

script.js 
function returnValue('my argument'){
  var echo = returnvalue();
  return 'my argument';
}

You are trying to define a new function, to call a function with an argument you can just do this:

function returnValue(argument) {
  return argument;
};

var echo = returnValue("My argument");

Your solution for task 1 was on the right track :) Task 2 asks you to pass the function a literal string value. This would look like this:

function returnValue(argument){
  return argument;
}

returnValue('My argument');

"Passing" something to a function essentially means putting it into the parenthesis when you call it. Instead you replaced the arguments inside of the function definition, which wasn't what the task meant, and which broke task 1 - because a variable name can't have quotation marks around it.
