When you post code, compiler error messages or serial monitor output to the forum you need to put triple backticks at the beginning and end of the code etc to ensure that it displays correctly.
Triple backticks look like this:
```

As far as your compilation error is concerned, you should read this link:

How to fix compiler problem - #error “Please specify your BLYNK_TEMPLATE_ID and BLYNK_TEMPLATE_NAME”

I see posts from people who are experiencing the compiler error that says: #error “Please specify your BLYNK_TEMPLATE_ID and BLYNK_TEMPLATE_NAME” There are three possible causes for this error… The lines of code that specify the BLYNK_TEMPLATE_ID BLYNK_TEMPLATE_NAME are commented-out with double forwarded slashes (//) that turn these lines into comments rather than lines of code, like this…. /* Fill in information from Blynk Device Info here */ //#define BLYNK_TEMPLATE_ID "TMPxxxx…

In future, it would probaly help if you did a quick search of the forum before posting your problem, as there’s a good chance that the answer is already available to you.
