Subject: Date formats
guys,
i am working on a tap3 web app. i want to implement a drop down menu
with various date formats (like DDMMYYYY etc.). the user selects one,
clicks on submit and the system uses this date format everytime now.
i am currently working on the drop down page. can somebody help me out
with the logic behind taking the entry and formatting the dates
accordingly. thanks.
