Is not a valid integer value
Buenos días,
Estoy realizando una pequeña aplicación con una serie de radio button los cuales tienen un valor númerico i el resultado sale reflejado en un text, el codigo que utilizo es el siguiente:

Código Delphi [-]
unit eqt;

interface

uses
  Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics,
  Vcl.Controls, Vcl.Forms, Vcl.Dialogs, Vcl.Imaging.jpeg, Vcl.ExtCtrls,
  Vcl.StdCtrls, Vcl.DBCtrls, Vcl.Mask;

type
  TForm12 = class(TForm)
    Label2: TLabel;
    logo: TImage;
    Label7: TLabel;
    DBRadioGroup1: TDBRadioGroup;
    DBRadioGroup2: TDBRadioGroup;
    DBRadioGroup3: TDBRadioGroup;
    DBRadioGroup4: TDBRadioGroup;
    DBRadioGroup5: TDBRadioGroup;
    DBRadioGroup6: TDBRadioGroup;
    DBRadioGroup7: TDBRadioGroup;
    DBRadioGroup8: TDBRadioGroup;
    DBRadioGroup9: TDBRadioGroup;
    Label1: TLabel;
    DBEdit1: TDBEdit;
    Button1: TButton;
    Button2: TButton;
    procedure Button2Click(Sender: TObject);
    procedure DBRadioGroup1Change(Sender: TObject);
    procedure DBRadioGroup2Change(Sender: TObject);
    procedure DBRadioGroup3Change(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form12: TForm12;

implementation

{$R *.dfm}

procedure TForm12.Button2Click(Sender: TObject);
begin
Close;
end;

procedure TForm12.DBRadioGroup1Change(Sender: TObject);
begin
  //showmessage(form12.DBRadioGroup1.Value);
  //showmessage(form12.DBRadioGroup2.Value);
  //form12.DBEdit1.Text := string(form12.DBRadioGroup1.Value) + string(form12.DBRadioGroup2.Value);
  //form12.DBEdit1.Text := IntToStr(TryStrToInt(form12.DBRadioGroup1.Value)+ StrToInt(form12.DBRadioGroup2.Value)+ StrToInt(form12.DBRadioGroup3.Value) + 
  //  StrToInt(form12.DBRadioGroup4.Value) + StrToInt(form12.DBRadioGroup5.Value) + StrToInt(form12.DBRadioGroup6.Value) + StrToInt(form12.DBRadioGroup7.Value)+ 
  //  StrToInt(form12.DBRadioGroup8.Value)+ StrToInt(form12.DBRadioGroup9.Value));
  form12.DBEdit1.Text := IntToStr(StrToInt(form12.DBRadioGroup1.Value) + StrToInt(form12.DBRadioGroup2.Value) + StrToInt(form12.DBRadioGroup3.Value));
  end;

procedure TForm12.DBRadioGroup2Change(Sender: TObject);
begin
  form12.DBEdit1.Text := IntToStr(StrToInt(form12.DBRadioGroup2.Value)+ StrToInt(form12.DBRadioGroup1.Value)+ StrToInt(form12.DBRadioGroup3.Value));
end;

procedure TForm12.DBRadioGroup3Change(Sender: TObject);
begin
  form12.DBEdit1.Text := IntToStr(StrToInt(form12.DBRadioGroup3.Value)+ StrToInt(form12.DBRadioGroup1.Value)+ StrToInt(form12.DBRadioGroup2.Value));
end;

end.

Y cada vez que escojo un radio button me sale el siguiente mensaje: '''' is not valid integer value, en cambio me realiza la suma bien y el resultado aparece en el text, alguién se le ocurre que es lo que esta fallando.

Gracias.

Que en todos estás añadiendo un strtoint que no sirve porque ya es un integer
Código Delphi [-]
StrToInt(form12.DBRadioGroup2.Value)
Sobra ese strtoint, ya que ese Value es un integer

Más bien parece que esos form12.DBRadioGroupN.Value a veces son cadena vacía (''), y por eso te marca error la función StrToInt.

Si quieres convertir a entero una cadena que podría no representar un entero, puedes apoyarte en la función TryStrToInt (no sin modificar un poco tu código).

Buenos días,
Realice un showmessage de los diferentes radio button i todos devuelven un numero, ninguno de ellos devuelve una cadena en blanco.

Si quito los StrToInt 
Código Delphi [-]
form12.DBEdit1.Text := form12.DBRadioGroup1.Value + form12.DBRadioGroup2.Value + form12.DBRadioGroup3.Value;
no se realiza la suma de los valores de los radio buttons, es decir, si escojo a tres radio button que su suma vale 5, así como pongo la instrucción de arriba el resultado es 122, no los suma los concatena.

No lo entiendo.

Se le ocurre a alguien alguna cosa.

Gracias.

Cierto, .Value es un string, debes hacer el StrToInt.
El problema es el que te indica Al González, algún TDBRadioGroup no tiene asignado nada, por lo tanto es una cadena vacía.
