ERRORLEVEL test not working properly MS DOS Batch Script (windows 2003 server)

Problem: DOS Batch script below incorrectly executes the "SUCCESS" label even though results show that the
ERRORLEVEL is returning an exit code of " 20".

Please note I have included both the following:
#1 resulting log file
#2 the script

#1>>>Here is the resulting log file
