Where you ve written  OffenceBox Text     you need to replace this with  OffenceBox Text   It s a property  not a method - the clue s in the error

It have happened because you are trying to use the property  OffenceBox Text  like a method  Try to remove parenteses from OffenceBox Text   and it ll work fine   Remember that you cannot create a method and a property with the same name in a class     By the way  some alias could confuse you  since sometimes it s method or property  e g   Count  alias     Namespace  System Linq  using System Linq  namespace Teste       public class TestLinq               public return Foo                         var listX   new List lt int gt                 return listX Count x   gt  x Id    1                         Namespace  System Collections Generic  using System Collections Generic  namespace Teste       public class TestList               public int Foo                         var listX   new List lt int gt                 return listX Count                         Source - Linq  https   msdn microsoft com library bb338038 v vs 100  aspx Source - List   https   msdn microsoft com pt-br library 27b47ht3 v vs 110  aspx

I had the same issue and realized that removing the parentheses worked  Sometimes having someone else read your code can be useful if you have been the only one working on it for some time   E g     cmd CommandType   CommandType Text       Replace        cmd CommandType   CommandType Text

As the error clearly states  OffenceBox Text   is not a function and therefore doesn t make sense
