1.) Great work! I believe that you may very well have achieved the goal you mentioned to me of making your previous work look... <ahem> shoddy.
2.) Many thanks to Aureus. Anyone that was actually able to provide assistance to Ludic gets major cred in my book.
3.) I notice that there are some non-obvious tabs listed. Can either of you explain, in brief, what differences, if any other than formatting, there are b/w the Simple Attack Calculator v/s the Advanced Calculator?

Thanks to you both. You do good work.
