I want to create a set of 'check boxes' and I want one of them to have overall control over all others - so when you check it, every other check box gets checked, if you uncheck it, then you can check individual check boxes as needed. For example, if I have a set of data such as: 'All Years' and then 2001, 2002, 2003, 2004. If the checkbox corresponding to 'All years' is checked, then, I want rest of the four checkboxes to be checked as well. If not, then, I want to be able to individually check / uncheck the remaining four checkboxes. Is something like this possible in Excel 2007? This is for the visual aspect - I can already make the resulting data (TRUE/FALSE) to act as needed - but visually, I cannot make it work. Any ideas out there?
