[Samba] Mount share in Ubuntu

[Henry]

I have a samba server with three shares.
I would like to permanently mount one of these shares in a Ubuntu
server. I have read the following guide:
https://wiki.ubuntu.com/MountWindowsSharesPermanently#Mount_password_protected_network_folders

This guide states that I need to amend fstab and then use "mount -a"

I have included the following in fstab:
//aphrodite/Personal /mnt/samba_personal cifs
username=henry,password=":)",iocharset=utf8  0  0

When I try to mount this share I get:
root at pve:~# mount -a
mount error(13): Permission denied
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

I know the username & password are correct so am unsure of what the
problem may be.
