"Invalid syntax in 'Order By' parameter."

"Invalid syntax in 'Order By' parameter."

  
I am trying to use  "List_SortCilumn" but getting error "Invalid syntax in 'Order By' parameter."
Please help..
Should it be "List_SortColumn" instead (a simple misspelling)?
Actually, mine end up using the following (substitute TableName.Id, {Table} and [columnname] with your values):
List_SortColumn_GetOrderBy(TableName.Id, "{Table}.[columnname]")
