Hi all,

I've a requirement wherin i have to validate a date field in my adobe form.

-> Firstly it has to pop up an error message if at all the field is empty.

-> Secondly it has to pop up an error message if the entered date is less than today's date.

-> Thirdly, it has to pop up an error message if the entered date is >30days from todays date.

The date format am using is YYYYMMDD.

Please help me out.

Have you looked at the 'Date2Num()" and "Num2Date()" functions. One could take the date to validate and use the "Date2Num()" function to convert it to the number of days since the epoch date or 0 if an error and then use the "Num2Date()" to convert the number of days back to a string. Now compare the string for equality, if false the validation failed.
