Whats wrong with this code?

http://codepen.io/anon/pen/AqvGJ

Its basically supposed to give a warning pop up when you first appear and then after putting words in the box and clicking Click Me its supposed to change the H1. Any thoughts? Total noob here.

Solved. Forgot to put curly brackets after substitute by onclick

You're missing the parentheses in your function call (substitute() rather than substitute):

input type="submit" value="Click Me" onclick="substitute()" />

See my fork for a working example

Scott thanks. We must have posted at the same time.
