In the example, the only thing I see connecting the two forms is the URL addition of ?bFile=Mailboxes&bKey=Key&IDField=MAI__MailboxNumber&Change_btn=Change&
2 questions -
1 - Are the parameters bFile, bKey, IDField, and Change_btn Standard parameters for the webForm template to set the current record to display?
2 - Can they be used in forms?
3.. THREE questions there are 3 questions - Are there other standard parameters?
4. AArgh ! 4 questions - Can these be used to embed a sub form in a form?
thats it for now
If this is documented somewhere, let me know.
