Call the new sayHi function you just created?

i write sayHi (); but says communication error

Hi Daniel, Could you paste the code for us, hard to guess what might be happening.

function sayHi(arg) {
alert(arg);
}

Ok, the function is expecting you to pass a string and then it gets alerted, this is what the 'arg' is. The following code will work:

function sayHi(arg) {
  alert(arg);
}

sayHi("Hey there!!");
