If you never educate yourself, you will keep asking the simple question you
asked. If you want to be continually dependent on others, do so. I always
buy books, read, try to find the answer for myself and when I cannot, I ask
others. I have been teaching for over 40 years. What I find most is that
people will not read the manual. They find reading to be too hard. So they
ask others rather than even trying to read. I feel sorry for them. A very
good book for you to buy has been written by John Walkenbach. I do not know
what version of Excel you have since you didn't consider it important to
enlighten us. If you had I could have given you the ISBN of his book. The
books he writes are about $40 (U.S.). Happy reading!
