You have to do it in steps:
1) Query the database to obtain the filed values (or pass them via URL to the new page)
2) In the HTML objects, set:
a) TEXT: VALUE="<? echo $Text_field_value; ?>"
b) SELECT: You have to set SELECTED for the option you want to display
c) TEXTAREA: Like this:
<TEXTAREA><? echo $Textarea_value; ?></TEXTAREA>
d) CHECKBOX AND RADIO: Set them to CHECKED to make 'em appear selected.
Hope this helps
