Okay, It looks like you're using Chrome, in which case the text box field has some issues, you'll need to use the Chrome feature of extending the input area(using the little tab in bottom right-hand corner), then ensure that the code is all on one line, then hit preview or update. (Note that after you preview the size of the input area reverts back to default, this means you'll need to resize it again for when you click update.)
