Adding Previous Month To Filename

Dear experts,

I'm using solaris 5.10 and bash. I want to zip file "Amount.txt" to "Amount.zip" and rename it to "Amount_<prev_month>_<this year>.zip". For example, file for this month should be renamed to "Amount_06_2012.zip", for next month it should be "Amount_07_2012.zip". I have no problem for zipping the file. Here's the script but it's not working:

Code:
month=`date +%m`
year=`date +%Y`
lmonth=`expr $month - 1`
if test "$lmonth" = "0"
then
lmonth=12
year=`expr $year - 1`
fi

mv Amount.zip Amount_`$lmonth`_`$year`.zip

When I executed it, it shows:
Code:
./script.sh: 6: not found
./script.sh: 2012: not found

Then the zip file renamed to "Amount__.zip"

Best regards,
Kris Adrianto
