I don't know Why do code

Code:

PHP:

public function createmoney(Player $p){
   $config = new Config($this->getDataFolder() . "config.yml", Config::YAML);
   $form = new CustomForm(function (Player $p, $data = null){
    if($data === null){
     return true;
    }
    $amount = $data[2]*$data[3];
    $money = $this->eco->myMoney($p);
    if($data[1] === null){
    if($money >= $amount)
        {
            $this->eco->reduceMoney($p, $amount);
      $this->getLogger()->info("Connect this function");
     $money = $data[2]*$data[3];
     $rand = mt_rand(0, 99999);
      $code = md5($rand);
      $giftcnf->set($code);
      $gift->setNested($code . ".type", "money");
      $giftcnf->setNested($code . ".data", [
       "amount" => $money
       ]);
       $giftcnf->setNested($code . ".use", []);
       $giftcnf->save($p, $code);
      $this->showcode($p);
    }else{
   $p->sendMessage($config->getNested("language.nomoney"));
      }
    }else{
            if($money >= $amount)
        {
            $this->eco->reduceMoney($p, $amount);
      $this->getLogger()->info("Connect this function");
     $money = $data[2]*$data[3];
      $giftcnf->set($code);
      $gift->setNested($code . ".type", "money");
      $giftcnf->setNested($code . ".data", [
       "amount" => $Money
       ]);
       $giftcnf->setNested($code . ".use", []);
       $giftcnf->save($p, $code);
      $this->showcode($p);
    }else{
   $p->sendMessage($config->getNested("language.nomoney"));
      }
    }
   });
   $form->setTitle($config->getNested("language.formtitlecreatemoney"));
   $form->addLabel($config->getNested("language.formlabelcreatemoney"));
   $form->addInput($config->getNested("language.formoneycreatemoney"));
   $form->addInput($config->getNested("language.formamountcreatemoney"));
   $form->addInput($config->getNested("language.formcountcreatemoney"));
   $form->sendToPlayer ($p);
  }

I set my money 9999999 and i set input(2) 3 and input (3) 2
but no send anything

 

Just dump the $data variable using var_dump, you'll see the contents. Learn to debug!
