Thank you for your assistance, I have managed to get the
button working fine now.

I have a workbook with many worksheets(25), on one
worksheet is a command button that when clicked locks
all
cells in all worksheets, once all the data required is
entered. What I need is to disable this button until a
cell on the first worksheet has a specific value, can
anyone please help with the necessary code or macro?

The appropriate cell is E41 on sheet1, it has to have
the
value "For Contract" to allow the button to be used.

Thank you in advance for any assistance.
