Hi

I’m very new to javascript and stuck on something that might be fairly elementary!
What i want to do is add predefined text to a text area on click of an button (add). I also want to be able to remove it on clicking on another button (delete) I understand roughly what I’m doing here but the DOM has me stuck. Please can anyone help a frustrated newbie?
