Looks like you have mistaken the correct syntax here.
Please verify with the IOS command reference for your release. I have done this as well but while that is for registered users only the link will be of little use to you. This is the representation of what i looked up:
ip nat inside source {list {access-list-number | access-list-name} | route-map name} {interface type number | pool name} [mapping-id map-id | overload | reversible | vrf name]
The | means "OR". Basically the command "ip nat inside source static" is followed either by the keyword "list" or the keyword "route-map". The command you have constructed seems incorrect to me.
