I was attempting to create a pie chart and clicked the pie chart icon.
However, did not want it embedded in the same Work sheet, so I clicked on the
new work sheet tab. It did not work and somehow I must have triggered
something else and all icons on both my insert tab and data tab is greyed out.

Hi,

There are mainly 5 reasons for insert button grayed out.
1.File is shared
2.File is Protected
3.Multiple sheet selected
4.Display Options disabled
5.Track changes enabled
More information is available on this website with how to check these and fix it: http://www.askeygeek.com/deselect-mu...developer-tab/

Hope this helps
Thanks,
