why can't i insert a chart in excel worksheet?

[Joy]

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!!

Is the worksheet protected? Is it shared? Is it grouped (are more than one
sheet selected)?

I have the exact same problem. The sheet is not however shared (don't know how to check that though), or protected. What can I do?

Thanks!
