I stuck on using option button groups. I have created two option button groups and a date cell on a worksheet that I want to use working with 12 monthly calendars. Group 1 has 4 choices (Weekly, Bi-Weekly, Semi-Monthly, and Monthly), Group 2 has 7 choices (days of the week), and then there is the cell to enter a date. What I want to do is make select in Group 1 and Group 2 and enter a date, then have programming set calendar dates (identified in group 1 & 2) font a pre-defined color. For example, if select Weekly in group 1 and Sunday in group 2 and enter date of first Sunday of year, then Sunday of every week will be the pre-defined font color. Or, if I select Bi-Weekly and Friday and enter 1/8/2010 (second Friday of year), then Friday 1/8/2010 and every other Friday is the pre-defined font color. Each of the choices from group 1 seems to present different problems, and I have no idea how to begin programming for the desires results. Any help is so greatly appreciated. <?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o></o>
