Outlook Appoinment Form customised but values of the user defined or custom
fields not found on the calendar

I have customized the appoinment form (with a new tab and 2 dropdowns) and
published the same to my "Personal Forms Library"
Also made an entry with the same to show an item in my calendar. I then use
VBScript to fetch all the items in the calendar but i do not find the Project
& Task data (custom/user defined field)

Im not sure if i am missing something here ? Please do let me know
