SessionId
The SessionId tag is used with the more sophisticated gift orders that allow entry of order information on more than one page, confirmation pages,
forms for modifying donor or recipient information, or adding more recipients.
This tag should NOT be used on the initial entry page, but on the custom replies only. After order information is entered
on the initial entry page, it is stored in a session created in memory while additional modifications to the order can be made.
If for any reason the session information is destroyed, ITPS can detect this to give a more meaningful error message.
The value should only be set using the ||SessionId|| substitution variable.
Value's Maximum Length:
NA
Typical Syntax in Custom Reply:
<input type=hidden name=SessionId value=||SessionId||>
