ledPin was not declared in this scope, unsure why?

I have recently brought an ESP 32 WROOM, and ive been watching a video by Drone workshop, i copied his blink sketch from the article Getting Started with the ESP32 - Using the Arduino IDE
when i try to upload it the IDE tells me ledPin was not declared in this scope, however I have been staring at this for nearly 10 minutes and it looks fine to me, ill show a print screen here as it is a very short sketch and you can see all the code in one screenshot.

here is the complete error message:

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

very odd, under board in tools I use "ESP 32 devmodule" there are also a variety of new setting that appear when using the ESP 32 and ill show an image of my setting here, hopefully its clear.

thanks for the help!

Look at the top of the code, things like esp32-blink are highlighted, so the IDE thinks its code.

If your screenshot is the whole code, there is something missing.

The starting comment does not have a start, only the end.

I doubt that the compiler is happy with that.

I have recommended to the moderators to move your thread to a more appropriate section.

Can you please post your code, rather than screen captures

I'm not 100% sure as i'm not an expert in coding but apart from the comment, can you maybe use #define ledPin 2 or does that not make a difference?

The problem is almost certainly that the code does not start with a /*, but since the OP only posted a picture of part of the code, it's hard to tell.
It is likely that #define wouldn't have worked either.

Think we need to know what is going on here first.
Looks like a copy and paste code.
