The code example needs:

method="post"

in the form tag.

Re: duplicate UUIDs, note that *certain*substrings* of CreateUUID() may be the same from invocation to invocation: the UUID is based on date, machine ID and a random number, but it isn't hashed to make one UUID different, character by character, from the next and previous ones.

Only the whole UUID will be unique: are you sure you'renot taking a substring to use as a token?

I'm a newbie... used CreateUUID() but notice that duplicate IDs occur although clients, sessions, and time at generation is completely different. Now, I've added a check to make sure the UUID generated doesn't exist in the database before I insert the new record. I couldn't find any solutions out there, so thought I post this note, so other newbies that encounter the same problem know that this problem exists. Is there any other way to prevent duplication? Cheers.

try the follow code
#CreateUUID()#
the formate is 8-4-4-16, therefore , it is a 35 character string

The description of the format is incorrect. The documentation states "The character groups are 8-4-4-4-16.", but it's really 8-4-4-16. The incorrect statement would therefore make the UUID a 40 character string instead of a 35 character string.
