Unsupported Command Found - when loading PDM - Cisco PIX Firewall

I inherited a cisco pix firewall network and I know very basic cisco commands.  I manage other firewalls and vpn (checkpoint, etc.) but am unfamiliar with pix except basic stuff.  I had some help getting the PDM installed.  In loading it, I am only able to monitor and view and not make config changes.  The error is
"Unsupported Command Found
PDM has encountered a PIX firewall configuration command statement that
PDM does not support.............
"access control list vpnrule is applied to interface for outside nat 0  and vpn client group VPNTunnel for split tunneling.  PDM does not support multiple uses of a given access control list."

I don't want to change this without knowing what I am doing as I don't want to break anything.
Here is a copy of the config.  Any help would be highly appreciated.

Pretty simple to overcome:
> access-list vpnrule permit ip

Add this:
 access-listnat_zero permit ip
 no nat (inside) 0 access-list vpnrule
 nat (inside) 0 access-list nat_zero

Do I then delete this rule?
> access-list vpnrule permit ip

what about this rule?
vpngroup VPNtunnel split-tunnel vpnrule

No, keep it. You will then have 2 acls that are essentially the same.
1 applied to nat 0
1 applied to the split-tunnel
PDM is happy

Thanks!   This worked like a charm.
In case anyone views this, the command was missing a space between ...list and nat...
access-list nat_zero permit ip
