I have created a visual Force page having a Flow in it. I am trying to create new ACCOUNT record using "Sites". But I am getting following Error on Record Create Stage in the flow.

Error occurred attempting to get data type for : RawFieldImpl[tableName: Account, columnName: Country__c] > CREATE
caused by element : FlowRecordCreate.t_acnt_create2
caused by: Error occurred attempting to get data type for : RawFieldImpl[tableName: Account, columnName: Country__c] > CREATE.

When i try to create new account using "preview" option on "Sites" its working fine and new record is being created in Account Object.
But i access it using "Site" url. Its giving above mentioned Error.

I dnt know what am i missing?
