Script for Transfering Database Diagram

I've been trying to get the scripts posted earlier to the group by
Clay Beatty to work properly. Using the three components he posted, I
have managed to get a new SP generated. However, when I paste this
scrip into a new copy of the original database (different name, same
structure as a test), I get an Invalid Object Name for the temp table
#PersistedVaria bles.

Has anyone run into something like this before? Or used the scripts I
mentioned successfully? Help would be appreciated. The resulting
section of code causing the error is posted below. This is running on
SQL-Server 2000.

CREATE PROCEDURE [dbo].[Create Diagrams] AS

------------------------------------------------------------------------
-- Database Diagram Reconstruction Script
------------------------------------------------------------------------
-- Created on: 2004-07-19 11:54:43.327
-- From Database: CABIN
-- By User: dbo
--
-- This SQL Script was designed to reconstruct a set ofdatabase
-- diagrams, by repopulating the system table dtproperties, inthe
-- current database, with values which existed at the timethis
-- script was created. Typically, this script would be createdto
-- backup a set of database diagrams, or to package up thosediagrams
-- for deployment to another database.
--
-- Minimally, all that needs to be done to recreate the target
-- diagrams is to run this script. There are several options,
-- however, which may be modified, to customize the diagrams tobe
-- produced. Changing these options is as simple as modifyingthe
-- initial values for a set of variables, which are definedimmediat ely
-- following these comments. They are:
--
-- Variable Name Description
-- -------------------------------------------------------------------
-- @TargetDatabase This varchar variable will establishthe
-- target database, within which thediagrams
-- will be reconstructed. This variableis
-- initially set to database name fromwhich
the
-- script was built, but it may bemodified as
-- required. A valid database namemust be
-- specified.
--
-- @DropExistingDi agrams This bit variable is initially setset to a
-- value of zero (0), which indicatesthat any
-- existing diagrams in the target
-- to be preserved. By setting thisvalue to
-- one (1), any existing diagrams inthe target
-- database will be dropped prior to
-- reconstruction. Zero and One are theonly
-- valid values for the variable.
--
-- @DiagramSuffix This varchar variable will be usedto append
-- to the original diagram names, asthey
-- existed at the time they werescripted. This
-- variable is initially set to take onthe
-- value of the current date/time,although it
-- may be modified as required. Anempty
string
-- value would effectively turn off thediagram
-- suffix option.

I'm not familiar with this code, but it appears to start out as a procedure,
and then turns into a series of TSQL batches. When the first GO command is
reached, this executes the CREATE PROCEDURE statement with the code up to
that point as the procedure text. Subsequent sections between GO commands
are executed as independent batches, however since the #PersistedVaria bles
table is created in the procedure, not in a batch, it doesn't exist when the
batches try to find it.

I can't really say more than that, as I don't know how this procedure is
intended to be used - you may want to review the original posting again. By
the way, a procedure name with a space in it is probably a bad idea, as many
tools (and many human beings) don't always handle that very well.
