if(!response) You show the old dialog
if(response) You show the new dialog
Think about continuous dialog, when you click Select it will use the response, however when you click Back it will use !response, there should be the code for going back to any dialog..

pawn Код:

switch(dialogid)
{
    case DIALOG_MENU:
    {
        if(!response)
        {
            // Go Back
            return 1;
        }
