The new print method can only be called once, otherwise, the newly added content will override the current content.

I was using the print function in multiple spots instead of saving to a variable. Is there a way to append with the innerHTML method?

:point_right: You can append, but you need to be careful.

You can certainly write that assignment statement as an append instead:

  outputDiv.innerHTML += message;

But you have to be careful that neither the current contents, nor the new message content being added, have tags (or are missing tags) that will cause the concatenated HTML to not make sense. If the element contains only text, and you're adding only text, you'll most likely be safe.

Thanks Steven, I'll use that in the future (with care!).
