Need help fixing code please

Noob here, can anyone help me?

"‘timer_count’ was not declared in this scope"

Error is in void setup on the "MsTimer2::set" line

If i remove this, the code compiles
` // PWM specification setting
TCCR1A = 0b00100001;
TCCR1B = 0b00010001;//分周比1

// PWM setting
OCR1A = (unsigned int)(8000000 / frq );

//for development
// Serial.begin(9600);
}`

 //開発用

 Serial.print(ext_count);
 Serial.print(",");
 Serial.print(CH1out * 500);
 Serial.print(",");
 Serial.print(D_count_ch1 * 80);
 Serial.println("");

}

//タイマーカウント。1ms毎にカウントを増やす
void timer_count() {
 ext_count ++;
}

Is that the only error message?

where is the '{' here?

}

// PWM specification setting
TCCR1A = 0b00100001;
TCCR1B = 0b00010001;//分周比1

// PWM setting
OCR1A = (unsigned int)(8000000 / frq );

//for development
//  Serial.begin(9600);
}

yeah, that i know of

oops, now it says
"expected unqualified-id before '{' token"

i tried combining 2 working codes together

I'm sorry, I find that hard to believe.

i could be wrong, again im a noob

Combining, or cut and pasting? Because what you have looks like a cut and paste error. But most attempts to merge code without understanding it, don't succeed.

In general combining 2 sketches require knowledge of how each sketch works and often involves restructuring to avoid hardware, timing, and/or resource conflicts.

rodger that, i just cut and paste. i have no clue what im doing haha. luckily it works

Now.
