I'm trying to make a block that you can take items out of and put them in, but if you have an axe it will craft an item. But it's running multiple times, I believe because clientside and serverside are both using the same code. Can someone help me make this code work?

 

public class WorkStation extends Block implements EntityBlock  {
	
	public WorkStation(Properties props) {
        super(props);
    }
	
	
	@Override
	public InteractionResult use(BlockState state, Level level, BlockPos pos, Player player, InteractionHand handIn,
		BlockHitResult hit) { //When the block is clicked
		if (!level.isClientSide){ //If server side
			player.sendMessage(new TextComponent("Not client side"), player.getUUID());
			ItemStack item = player.getItemInHand(handIn); //Get Item in hand
			BlockEntity currentBlockEntityInstance = level.getBlockEntity(pos);
			if (item.isEmpty()) { //If there is no item
				player.sendMessage(new TextComponent("hand empty"), player.getUUID());
				if (currentBlockEntityInstance instanceof WorkStationBlockEntity workstation) {
					Container currentWorkStationInventory = workstation.getItemHandler();
					for (int i = 0; i < workstation.inventorySize(); i++) {  //Loop through the workstation inventory
						if (workstation.getItemHandler().getItem(i).isEmpty()) { //If an Item is empty
							if(i > 0) { //If the index is not 0 (so that we don't index a negative number)
								player.setItemInHand(InteractionHand.MAIN_HAND, workstation.getItemHandler().getItem(i-1)); //Put the last item (the one before we hit the empty spot) in the players hand
								workstation.getItemHandler().setItem(i-1, ItemStack.EMPTY); //Remove this item from the workstation
								level.playSound(null, pos, SoundEvents.WOOD_BREAK, SoundSource.BLOCKS, 0.1F, 10F);
								return InteractionResult.SUCCESS; //End the sequence
							} else { //If the item will be negative then end
								return InteractionResult.FAIL;
							}
						}
					}
					return InteractionResult.FAIL;
				} else {
					return InteractionResult.FAIL;
				}
			
			} else { //If there is an item in the players hand
				player.sendMessage(new TextComponent("hand full"), player.getUUID());
				if(item.getItem() instanceof AxeItem) { //If the player has a n axe in their hand (if the item is an axe)
					player.sendMessage(new TextComponent("hand has axe"), player.getUUID());
					if (currentBlockEntityInstance instanceof WorkStationBlockEntity workstation) {
						Container inventory = workstation.getItemHandler();
						Optional<WorkStationAxeRecipe> match = level.getRecipeManager().getRecipeFor(WorkStationAxeRecipe.Type.INSTANCE, inventory, level);
						
						if(match.isPresent()) { //If there is a recipe
							player.sendMessage(new TextComponent("match present"), player.getUUID());
							Item outputItem = match.get().getResultItem().getItem();
							for (int i = 0; i < workstation.inventorySize(); i++) { //Go through workstation inventory
								workstation.getItemHandler().setItem(i, ItemStack.EMPTY); //make every item gone
							}
							workstation.getItemHandler().setItem(0, new ItemStack(outputItem)); //Put the output block in the workstation
							level.playSound(null, pos, SoundEvents.WOOD_BREAK, SoundSource.BLOCKS, 0.1F, 10F);
							return InteractionResult.SUCCESS; //End
						}else { //If there is no recipe
							return InteractionResult.FAIL; //end
						}
					} else {
						return InteractionResult.FAIL;
					}
				} else { //If the hand does not have an axe
					player.sendMessage(new TextComponent("hand has no axe"), player.getUUID());
					if (currentBlockEntityInstance instanceof WorkStationBlockEntity workstation) {
						Container currentWorkStationInventory = workstation.getItemHandler();
						for (int i = 0; i < workstation.inventorySize(); i++) { //go through the workstation inventory
							if (workstation.getItemHandler().getItem(i).isEmpty()) { //until there is an empty spot
								if(i < 11) { //as long if it's at eleven or under spots
									workstation.getItemHandler().setItem(i, item.split(1)); //set the spots item as the one in the players hand
									if (item.getCount() > 0) { //If the player has more than one item
										player.setItemInHand(handIn, item.split(item.getCount())); //Take away one from the stack
										level.playSound(null, pos, SoundEvents.WOOD_BREAK, SoundSource.BLOCKS, 0.5F, 50F);
										return InteractionResult.SUCCESS; //end
									} else { // If the player has just one item
										player.setItemInHand(handIn, ItemStack.EMPTY); //Empty the hand slot
										level.playSound(null, pos, SoundEvents.WOOD_BREAK, SoundSource.BLOCKS, 0.5F, 50F);
										return InteractionResult.SUCCESS; //end
									}
								} else {
									return InteractionResult.FAIL;
								}
							}
						}
						return InteractionResult.FAIL;
					} else {
						return InteractionResult.FAIL;
					}
				}
			}
		} else {
			player.sendMessage(new TextComponent("client side"), player.getUUID());
			return InteractionResult.FAIL;
		}
