chris, :~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ : From: CDitty : : I need to have a drop down box that lists : all the months of the year. In another box, : the days of the month. When the user changes : the month, the days drop down would be : automatically updated to reflect the correct : number of days for that month. :~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ the most important thing to know is what year do you want this to reflect. the number of days per month for february will be different based on your answer. i happen to have a solution that addresses all of this at once for you as it has month, day, and year dropdowns. i didn't happen to have something like this, but it took me about 10 minutes to write from scratch. http://members.evolt.org/jeff/code/days_in_month.cfm or for more fun, take a look at an ie5-only dhtml calendar widget i built http://members.evolt.org/jeff/code/calendar/ enjoy, .jeff http://evolt.org/ jeff at members.evolt.org http://members.evolt.org/jeff/
