Cannot get rsync script to backup files to USB

I have an rsync script which I use to backup my files to USB. Here is what the script looks like:

Code:len@len-satellitee45ta:~/Backup$ cat rsyncDriveFUSBBackup2.sh
rsync -avtu --modify-window=2 --exclude={'*.iso','Downloads','Desktop'} /home/len/* "/media/len/DRIVE F"
rsync -avtu --modify-window=2 /home/len/Documents "/media/len/DRIVE F"When I execute this script, this is the error message:

Code:len@len-satellitee45ta:~/Backup$ ./rsyncDriveFUSBBackup2.sh

I am operating in SparkyLinux. Screenshot also attached.

I cannot imagine what I am doing wrong. But surely you all can help. Thanks.
