Did you download the install script from below. or did you copy the sql code. I tried both install scripts on a server, and none of them failed with missing table value functions

-- -- # IMPORTANT!!!

-- #

-- # Because of the rather lengthy install script, I am only showing the

-- # script for display. It won't install, because of missing table value

-- # functions. The version I have shown is the 2008 version

-- # You can download a complete install script here.

-- # 2005 version - http://files.soendergaard.info/Install_spFixIndexNaming_V2005.sql
