somewhere around line 700 you'll see something similar to this:
rM_NAME = 0
rM_RECEIVE_EMAIL = 1
rM_AIM = 2
rM_ICQ = 3
rM_MSN = 4
rM_YAHOO = 5
rM_PM = 6
rM_TITLE = 7
rMEMBER_ID = 8
rM_HOMEPAGE = 9
rM_LEVEL = 10
rM_POSTS = 11
rM_COUNTRY = 12
rM_Avatar = 13
rREPLY_ID = 14
rFORUM_ID = 15
rR_AUTHOR = 16
rTOPIC_ID = 17
rR_MESSAGE = 18
rR_LAST_EDIT = 19
rR_LAST_EDITBY = 20
rR_SIG = 21
rR_STATUS = 22
rR_DATE = 23
if CanShowSignature = 1 then
rM_SIG = 24
end if
Make sure that no number is duplicated (eg. 2 sixes), and that they all follow each other.
