command isn't working in crontab

[Tomas Hulata <tombo@scs.sk>]

Hello, below command works in command line but not as a cronjob can 
someone explain me why?

23 58  * * *   root    cd /some_path/;mkdir "CAM1-$(date +%d.%m.%Y)";mv 
./CAM1/*.* ./"CAM1-$(date +%d.%m.%Y)"/;mkdir "CAM2-$(date +%d.%m.%Y)";mv 
./CAM2/*.* ./"CAM2-$(date +%d.%m.%Y)"/

I want to move files from /some_path/CAM1 directory to directory called 
CAM1-'today date' and the  same for /some_path/CAM2 directory
