I am using Excel 2007; I first added a group box and ensured that all my four radio buttons from FormControl ( Not Active-x) are placed within that group box and checked they are okay. One of my friends suggested that the linked cells are losing value because I am hiding and conditionally unhiding the rows in which these 12 groups are located. Another friend has suggested that instead of linking to cells , I link to a defined name which points to the cells. Both appear to work well for now. Many thanks.
