Private Sub CommandButton1_Click()
Run "Macro"
CommandButton1.Enabled = False

Hi Guys Dolls

I have a worksheet which is used for master data input - there is a Button
which when clicked generates a "Form" number via a Macro assigned to the
button. After generating the number I want to lock the button. I cannot use
Sheet Protect as I use it at the end of the worksheet when the last user
completes their input the Sheet protection is called via a Macro assigned to
a different button. the button is in Cell I5.

please could you assit with VBA code which would lock the Button after
number generation but leave the rest of the sheet unprotected for data entry.

Many thanks

Carl
