Using excel 2003. Cannot insert command button on a spreadsheet we have. Almost all icons in the control toolbox are unavailable when Im on this specific spreadsheet. Any new documents I open work fine. Is there some kind of protected spreadsheet that wouldnt allow for a button, picture, textbox label to be inserted???
I didnt make the original sheet but am just editing and improving it.

I would really appreciate any advice you could give, I have attempted to attach a jpg showing the greyed out icons in my controltool box

Thanks, John
