rdiff-backup errors: script keeps quitting with error - bash

Question

Ive recently been introduced to bash scripting... So, Ive used my advanced theft course to throw together the attached script. it runs... and exits with "/xxx/ not mounted. You are not root! I have rdiff-backup and sshfs installed and working. The commands work fine on their own on the commandline, but in the script, well... Can you guys take a look and lemme know? PS I copied a LOT of this from scripts I found here and a few other places.

# Prior to running this make sure you have ssh-keygen -t rsa to generate a key, then
# ssh username#target "mkdir .ssh/;chmod 700 .ssh"
# scp .ssh/id_rsa.pub username#target:.ssh/authorized_keys
#
# then check you can login and accept the ssh key
# ssh username#target "ls -la"
#
# Key things to remember, no spaces in pathnames, and try to use full paths (beginning with / )

# the --exclude ** / is a hack because it wont by default do multiple dirs, so use --include for all dirs then exclude everything else and sync / - if you dont understand dont worry
