I've been given a workbook which has radio buttons and combi-boxes (I think that's the name for these, similar to radio buttons but they appear with square tick boxes rather than round selection indicators, and you can select more than one). Please can you explain how to create, use and delete these, as Excel help gives no help on these? I'm using Excel 2003. The cells holding these seem to have a value of 1 if selected and 0 if not selected. The workbook contains radio bottons in cells B5 to B16, and combi-boxes in cells F5 to F21.
