Hi - we are new users to Zoho.  We're in Canada and we have provinces instead of states like in the US and India so calling it "Billing state" is a bit confusing for our users and we would to change that name.  Another example is your label "Billing code" which would more typically be called "Postal code". 

I would like to change labels where it is confusing to our users.  I found the layout editor for the form but am getting the message: "Can't edit property for system defined field".   Is that correct - there is no way to simply edit the label on a built in field?

Thanks
