Player interact event help

Ok so i made an event when a player clicks an enderchest it sends him a message but for some reason its sending the message with every block here is my code

Code:

    @EventHandler
    public void onInteract(PlayerInteractEvent e){
        Player who = e.getPlayer();
    if (e.getAction() == Action.LEFT_CLICK_BLOCK){
    if (e.getClickedBlock().getType() == Material.ENDER_CHEST);
            if (fileUtil.getSize(who) >= 45) {
                who.sendMessage(ChatColor.RED
                        + "Your bank is already the max size!");
                return;
            }

 

@dsdevil You have a semi-colon right after your if statement checking if the clicked block is an Ender Chest. I recommend learning Java before using the Bukkit API, but that's your problem right there.
