I have c shell code but give strange error

I have this c shell code but give strange error when I run it

echo "" > tmpfile
foreach priod ( 720 580 360 270 180 90 )
set fsize = `find -mtime priod | xargs ls -tg | awk '{ size += $4 } END {print size}' `
echo " ${priod} ${fsize}" >> tmpfile
end
end

it give this error

find: invalid argument `priod' to `-mtime'
find: invalid argument `priod' to `-mtime'
find: invalid argument `priod' to `-mtime'
find: invalid argument `priod' to `-mtime'
find: invalid argument `priod' to `-mtime'
find: invalid argument `priod' to `-mtime'

end: Not in while/foreach.


this code should be try to find All file and display them sort by time
I give example (( 720 580 360 270 180 90 ))
it go foreach period and add size and print it + the period
for example it goes for 270 fined all file from 180 day (6 month) add size of all file print period +size
like
180 2333345

and so on

like
30 3333523
60 4000000
90 5349943
120 6900000
150 7002345
180 80032443
210 92423243

It's been a while since I was foolish enough to write scripts for the c shell, but try putting a $ in front of your priod in the find command.

find -mtime $priod
