Grove 2-channel inductive sensor example sketch on arduino IDE LDC1612

Hello,
I’m facing the stray error issue while trying to compile the LDC1612 coin example. I tried clearing any spaces and auto formatted the code multiple times but nothing seems to help. I also tried to copy paste the code from your website but the stray error continues. I further tried to use the arduino web editor but that too hasn’t helped. Could you please help me fix this?

I have compiled it here with no problems, what development board are you using?

I’m using arduino UNO. Do you mind copy pasting your code here?

My code is exactly the same as yours, but I compiled it with Wio Terminal.

        }
 
        if(result_channel1<DISTANCE_15_20&&result_channel1>=DISTANCE_00)
        {
            Serial.println("The distance between the COIN is more than 2mm");
        }
 
    }
 
    delay(1000);
}

I have also tested it with Arduino UNO and it compiles with no problem. Attached is the code.
