Beginner - looking for assistance with functions

Just started a beginning web programming class and I'am working with JavaScript. My question is "how do you add a space between two variable alerts within a function?" The variables ask for first and last name and the function displays these two names but I am having difficulty adding a space between the first and last name when the "Greet" function appears. Any assistance is greatly appreciated. Here is the code:

Java isn't JavaScript, so you seem to have posted in the wrong forum. I've moved your post to the HTML/JavaScript forum though, so no worries!

That is a string, you are not adding variables together.

With a single variable it would be Greet(who1);

Thank you Eric. I appreciate your assistance.

use a two argument function ...

e.g. Greet(who1, who2)
