Hi - the first screenshot shows you failing because you do not need to add the (;) semi-colon after the function name 'Warning' as this is already in place in the code. And the second screenshot, the answer is 'arguments' - as in you can pass the function one or more arguments, like in following:

randomNumber(upper, lower);

For the third and fourth screenshots - you need to 'return' the variable message i.e. in the space you need to put the return statement followed by the message variable.

Ah yes, that makes perfectly sense, I missed it. Anyhow this doesn't work for greeting() nor greeting('name'). Any ideas?

EDIT - So tired I even totally missed your last sentence "For the third and fourth screenshots - you need to 'return' the variable message i.e. in the space you need to put the return statement followed by the message variable." Thats why I asked about the greeting()

Been coding for the whole day non-stop now.. Time to take a long break.

I deleted it. I believe Sam already had the correct answer, but that's no problem. I'll let him have the glory this time haha :P You're welcome, Vincent.

Vincent that is because it is not asking you to call the greeting function (as technically your are already inside the function itself) the challenge is asking you to return the message variable like this:

function greeting( name ) {
var message = "Hello " + name ;
return message
}

I hadn't explained it well but thanks Marcus.
