Self Taught Beginner of Excel

I have not been using Excel long and what I know I have learned on my own. I use Excel for personal use to maintain a 'Home Budget' program I created. Most of my concerns will probably be quite simple to most, but they're causing me to pull my hair out!?!? I have never joined a Chat forum like this before, so this is all new to me as well. I have about 3 questions that I need answers to and I'm not sure exactly how to post them. I suppose I'll learn as time goes on. Thanks for all of your help!
