Hi Peter,

What output are you after?

I tested your work and got this ''Hello Michael, my name is Andrew and I am in a awesome mood!"

Set the 'greeting' variable, on line 29, by using the 'genericGreet' function in the context of 'andrew' with the array of arguments, 'args1'.

this is the question and i believe that is the answer. at least thats what i have been shouting for.

You need to use the apply() method on the genericGreet variable like so:

var greeting = genericGreet.apply(andrew, args1);

thanks! that did the trick
