Simple Script - won't run - please help

Question

I've written a very simple script to check to see if a volume is mounted and then copy a directory to that volume if it is mounted:
#!/bin/sh
# check to see if network space mounted by looking for known folder
if [ -d /Volumes/backupvolume ]; then
cp –R /Users/username/Documents/foldertobebackedup /Volumes/backupvolume/username
fi
I made sure the cp command works by running it in the terminal - no trouble there.
According to what I see in Xcode, all the syntax is correct and there are no errors.
I then run the test on the script (per the Bombich instructions):
sudo u+x /Users/user/backupscriptingtests/190520100730.sh
I'm then required to enter the password (which I do and it accepts it)
The next thing that happens though is the following error appears:
sudo: u+x: command not found
Any ideas on what I'm entering incorrectly here? Eventually, this script will be a logout hook to copy files for a user as a backup. This process seems like it should be very simple, which is why I'd rather do it this way instead of buying a backup program.
Thanks!
FYI: The -d command has brackets, left bracket with space at the beginning and space with right bracket just before the ;

You need to include the actual backup volume name and home folder name where backupvolume, username, and user are. If the backup volume name contains spaces or other special characters, precede them with backslashes or put the whole path in single quotes.
