              1.) Use code tags when posting code.
              2.) Read the links that I posted above. The second one shows you how to read a file using two methods.

                  I'm sure you noticed that the compiler told you *what* symbol it can't find and on
                  *which* line it discovered this trouble; why didn't you transfer that information to
                  us? Do you want us to guess?

                  kind regards,

                  Jos
