Im stuck with this

"Set the value of echo to be the results from calling the returnValue function. When you call the returnValue function, make sure to pass in any string you'd like for the parameter. "

script.js
function returnValue("pa") {
  return pa;
}

var echo = returnValue("hi");

When you define a function, never put quotes around any parameter names (or around any variable names in general). This must have changed after you passed task 1. You also don't want to make any changes to the task 1 function during task 2.

Your other task 2 work looks good, so fix that and you'll pass.

got it thanks steven. the whole things still pretty confusing

I found it confusing to begin with. Just keep going and trust that if you do you will eventually get it. Seems like the confusion is about parameters vs arguments which definitely confused me to begin with.

When you declare the function: function returnValue(value) { return value; }

Here value in the brackets is a parameter.

When you call the function: returnValue("Hi");

Hi is now an argument being passed to the function.

Arguments can be string values, numbers etc (i.e. in quotation marks) parameters can't be string values (at least as far as I am aware).
