have the free text box for user to enter more than one email addresses. is there the way to validate those emails?
i normally validate one email from each box using the expresion but don't know how to validate more than one emails, can you help?
Sure but you are going to have to do the work to seperate the values in the text box into individual datam. Then you can validate these values.
The list functions would probably be helpful with the delimiter property to make any character(s) into delimiters such as spaces, bars, returns, line breaks, etc.
Then you can loop through the field as a list, extract each item and process and desired.
