I have created a worksheet and formattted it according to our textbook in
class. i am up to the point of inserting a chart, but when i go on the
ribbon to insert a chart the choices are greyed out and i can not insert a
chart. i opened a new worksheet to check, and the chart choices are not
greyed out. i also opened a previous worksheet and i can still insert a
chart, but i can not insert one in this worksheet for some reason. HELP!!
