How to work an if statement to FormAPI switch?

So I'm adding a result to switch but whenever I add an if statement, it doesn't work and acts as if whatever is below isn't there. When I end the if statement and run somethint else by itself, it works fine. I'm very confused, please help me.

 

can you provide your code?

 

PHP:

    public function onCommand(CommandSender $sender, Command $cmd, string $label, array $args): bool{
        $formapi = $this->getServer()->getPluginManager()->getPlugin("FormAPI");
        $form = $formapi->createSimpleForm(function (Player $player, int $data = null){
                    $result = $data;
                    if ($result === null) {
                        return;
                    }
                    
                    if($result === 1) {           
                       $chance = mt_rand(0,1); # For test purposes
                       if ($chance === 1) {
                           $this->getServer()->dispatchCommand(new ConsoleCommandSender(), 'enchant  '.$sender->getName().' efficiency 1');
                    
                       }
                    }
                
                    switch ($result) {
                        case 0:
                        break;
                    }
                
                    return;
    } );
            
        $form->setTitle("Random Enchants");
        $form->addButton("TEST");
        $form->sendToPlayer($sender);
        return true;
    }
}

 

PHP:

if ($result === 1){
$chance = mt_rank(0,1);
switch ($chance){
case 1:
$this->getServer()->dispatchCommand(new ConsoleCommandSender(), 'enchant  '.$sender->getName().' efficiency 1');
break;
}
}

I dont think you need that other switch
