I have created a formula which is using a custom setting. The formula works fine on developer edition vfp page , but not working with customer portal page. It gives #Error ! as value on Page. 

the formula field is like this :

$Setup.x1_alpha__MyConfig__c.x1_alpha__MyField  

Any idea, please let me know whats the problem in using with customer portal.

I have executed following query to retrieve owner details of the account,

Select a.Owner.Fax, a.Owner.Phone, a.Owner.Email, a.Owner.Title, a.Owner.Name, a.Owner.FirstName, a.Owner.LastName, a.Owner.Username, a.OwnerId From Account a

But somehow only following fields are retreived:

{Name=Demo System, Email=demo@akritiv.com, FirstName?=Demo, Id=005A0000000YnfSIAS,LastName?=System}  

You will see that Owner Name,Email values are coming but phone title etc are not coming. 

Anybody has any idea on this. Please let me know.
