script help Undefined /illegal variable using cat

Hello group,

Still fairly new at the whole scripting thing so be gentle. I'm trying to write a simple script that archives my log files into a master log broken into weeks of the year.

My script runs fine up till the "cat" lines which I get a undefined or illegal variable name error. But using the same format earlier in the script it has no problem with the makedir or touch lines with the dates in them.

I have fiddled with it & had no luck, can someone eyeball this and tell me what I have done wrong? This is on a freenas system using a version of freebsd which is why I have the kooky copy lines instead of just echoing "" to the logs, which seemed to break syslog.

TIA
DP

Code:

#/bin/bash
#by DP run as ROOT!
#
#  make directory in format week number-year.month-year-logs
#
mkdir /var/log/archives/'week-'$(date +%U'.'%B'-20'%y'-logs')
#
# touch new archived logs
touch /var/log/archives/'week-'$(date +%U'.'%B'-20'%y'-logs')/sshd.log
touch /var/log/archives/'week-'$(date +%U'.'%B'-20'%y'-logs')/system.log
#
#stop syslogd deamon
/etc/rc.d/syslogd stop
#
#copy sshd & system log to monthly directory
cat /var/log/sshd.log >> /var/log/archives/'week-'$(date +%U'.'%B'-20'%y'-logs')/sshd.log
cat /var/log/system.log >> /var/log/archives/'week-'$(date +%U'.'%B'-20'%y'-logs')/system.log
#
#copy clean sshd & system log file to clear logs
cp /var/log/clean/sshd.clean.log /var/log/sshd.log
cp /var/log/clean/system.clean.log /var/log/system.log
#
#
#restart syslogd
/etc/rc.d/syslogd start
#
# log results
logger SYSTEM "Daily rotation of SSH & System logs was successful stored in /var/log/week-"$(date +%U'.'%B'-20'%y'-logs')
#
# EOF

nislog

nislog(1M)						  System Administration Commands						nislog(1M)

NAME

       nislog - display the contents of the NIS+ transaction log

SYNOPSIS

       /usr/sbin/nislog [-h num | -t num] [-v] [directory]...

DESCRIPTION

       nislog  displays  the  contents of the NIS+ server transaction log on the standard output. This command can be used to track changes in the
       namespace. The /var/nis/trans.log file contains the transaction log maintained by the NIS+ server. When updates occur, they are	logged	to
       this  file  and	then  propagated  to  replicas as log transactions. When the log is checkpointed, updates that have been propagated to the
       replicas are removed.

       The nislog command can only be run on an NIS+ server by superuser. It displays the log entries for that server only.

       If directory is not specified, the entire log is searched. Otherwise, only those logs entries that correspond to the specified  directories
       are displayed.

OPTIONS

       -h num	 Display num transactions from the ``head'' of the log. If the numeric parameter is 0, only the log header is displayed.

       -t num	 Display num transactions from the ``tail'' of the log. If the numeric parameter is 0, only the log header is displayed.

       -v	 Verbose mode.

FILES

       /var/nis/trans.log    transaction log
