Hi I have this code to insert data to access with a ADOTable, but I get this error 'ADOT : canot perform tis operation on a closed dataset'

procedure TForm1.Button1Click(Sender: TObject);
Var
snaam,svan, swag, ssel : string;
begin
snaam := Edit1.Text;
svan := Edit2.Text;
swag := Edit3.Text;
ssel := Edit4.Text;

ADOT.Insert;
ADOT['Naam'] := snaam;
ADOT['Van'] := svan;
ADOT['Wagwoord'] := swag;
ADOT['Selnommer'] := ssel;
ADOT.Post;
