I have a web page that displays a weather-related image. I have 4 drop-down menus. 1) Time from 6:00 am to 6:00 pm every hour 2) a day selection (today, tomorrow, day after tomorrow) 3) image type (wind field at surface, wind field at 5000 ft, surface air temperature, cloudiness, etc). 4)location (Honolulu, La Serena, Chicago, LA, etc.) There is always one valid selection active in each drop down menu.
As individual selections are made, I'd like the appropriate image displaced.
Can't figure out how to do it ...
