"Create a function named returnValue that accepts a single argument then returns that argument. "

The challenge is : "Create a function named returnValue that accepts a single argument (you can name it anything), then immediately returns that argument.

I tried : var x=0; function returnValue (x) { x += 1; return (x); };

But it seems wrong... what do they expect from me ??

x += 1 is probably throwing it off. You don't need to do anything to x inside the function, only return it. I would remove that line, and you also don't need parentheses around x in the return statement.

The challenge wants you to return the argument without making any changes to it. You also don't want to make any assumptions about what type the argument will be.

This code both assumes the argument is a number, and then changes the value of it by adding 1.
