Why this code cannot compile

Using Arduino IDE, my esp32 code cannot compile. could not identify what the error is,
I have attached screenshot for this.

Please read the forum rules and advice and post accordingly.

The screen shot you show clearly shows there is an option to copy the error messages - use that as it make everything clearer and easier.

Without seeing your code it is almost impossible to work out what is causing your error, so post all you sketch (again read the forum guidelines), format accordingly and use code blocks.
