I have two tigra calendars for a start date and end date, and they put values into a text box. Is it possible to validate in the CALENDAR which dates people can select.<BR><BR>For example, I have a combo box with day, week, month in. If a user picks on day, they must be limited to the end date being one day from the start date. the same with week and month...i would like to highlight the dates which are allowed. e.g. a user clicks on week, then chooses the 2/9 as a start date. thus 9/9, 16/9 etc should all be allowed as end dates and no others.<BR><BR>Anyone know if this is possible??
