Is it possible to create a "Fake Pop-up"?

[Copperdog555]

Hello kind individual,

I was wondering if it might be possible (probably using the "script" function) to create a pop-up / error message. I have no comprehension of JavaScript, so some pointers would be much appreciated.

Thanks,
Copperdog

Figured it out. No need for this now.
