Shell Script to update JAMF Pro user infomation

I have made a script, with help from other scripts found online, that will take user input and then update user information on JAMF Pro.

All working apart from where you enter the staff/students full name for example "John Smith", script is only reading the first word on the input and updating JAMF = John.  Been on this for a few hours trying anything that I can find and now I am at a loss of what I can try to sort this.

Any help on this would be very welcome :)

JAMF_FULLNAME=`/usr/bin/osascript << EOT
tell application "System Events"
activate
set JAMF_FULLNAME to text returned of (display dialog "Please enter fullname " default answer "")
end tell
EOT`

#Store input full name
echo $JAMF_FULLNAME
