It appears a message showing : '' is not a valid integer value can anyone help me with this?


Here is the code for opening and Saving and The program


Opening:

var
Arquivo : TextFile;
X, Y : Integer;
Temp: String;
begin
if OpenDialog1.Execute then
 begin
  AssignFile(Arquivo,OpenDialog1.FileName);
  Reset(Arquivo);
   for X:= 0 to 9 do
    begin
      ReadLn(Arquivo, Temp);
      for Y := 0 to 9 do
        Area[Y, X] := StrToInt(Copy(Temp, Y + 1, 1))
    end;
    CloseFile(Arquivo);
    DrawGrid1.Refresh;
  end;
