Hi,
I am trying to add a column to a list based on concating 2 other columns of the same list, of which the first column is location , single line of text and the other is a site column added to the list called country.
formula i have tried =[country]&[location]
error:
One or more column references are not allowed, because the columns are defined as a data type that is not supported in formulas. at Microsoft.SharePoint.Library.SPRequestInternalClass.AddField(String bstrUrl, String bstrListName, String bstrSchemaXml, Int32 grfAdd)
