Validation message for password

Greetings,

I'm trying to currently place a validation message on the password within the Nop.Admin.  So far, I have added a rule to the CustomerValidator.cs file and checked on the message within defaultResources.admin.nopres.xml.  The validation does happen, however, I get the following message:

admin.customers.customers.fields.password.required

I'm uncertain where I would need to correct the message other than the xml file I mentioned.  Any help would be appreciated on the subject.  Thanks.

Kindest Regards,
Chad Johnson

Admin -> Configuration -> Languages -> View string resources -> Add new record

Use that full string you see now for the Resource Name and then type what you want it to say in the Value.
