The Function Buttons are Greyed Out in Numbers
I am new to Numbers having used Excel for years. I am trying to add up a column of figures but when I highlight the column and click the 'Function' button at the top of the page, all the functions are greyed out so not usable. Can someone tell me what I am doing wrong?
I am using Numbers 3.1, downloaded on Saturday.
Thanks
