/*************************************************************
Download latest Blynk library here:

Blynk is a platform with iOS and Android apps to control
Arduino, Raspberry Pi and the likes over the Internet.
You can easily build graphic interfaces for all your
projects by simply dragging and dropping widgets.

Downloads, docs, tutorials: http://www.blynk.cc
Sketch generator: http://examples.blynk.cc
Blynk community: http://community.blynk.cc
Follow us: http://www.fb.com/blynkapp

Blynk library is licensed under MIT license
This example code is in public domain.

You’ll need:

  • Blynk App (download from AppStore or Google Play)
  • NodeMCU board
  • Decide how to connect to Blynk
    (USB, Ethernet, Wi-Fi, Bluetooth, ...)

There is a bunch of great example sketches included to show you how to get
started. Think of them as LEGO bricks and combine them as you wish.
For example, take the Ethernet Shield sketch and combine it with the
Servo example, or choose a USB sketch and add a code from SendData
example.

You have code that is not inside of a function (those two if statements). All code (except global variable declarations, and function definitions themselves) must be inside a function. Ctrl+T will fix the indentation so it's easier to spot issues like this.

And yes, that compiler error is really uninformative.

In the future, post questions about coding in the programming help section, not the troubleshooting section - this section is for problems making the ide work, not help with your project. And use code tags to make the code easier to read and keep the forum from mangling it (like how it will change things into smily faces), and post the error as text not a picture.
