Command Button protection problems????

I have out together a workbook that contains several Command Buttons, but even though I have unlocked the command button when I protect the sheet I can't use the button, Excel keeps flashing up an error saying that it read only. I have been into tools-options and the read only tab is not checked. What am I doing wrong.

Please help

could you elaberate more, I don't quite understand what you mean,
where did you get the button from??
explain how you created the buttons??

I have used a Command Button from the control toolbox and linked a cell which gives me a True or False return which I need, but when I protect the work sheet the Command Button won't work. I get a message to un-protect the workbook before I can use it. I have been into the properties of the button and unlocked it, I just can't understand why It will not let me use it.

Hmm!, I can't get that to happen!
are you still in design mode??
