Hey guys I'm getting an error that is im pretty sure to do with how i am initializing my variables. It is: exit status 1 'threshold' does not name a type

Here's my code:

//Global Variables for moving max:

int analogValues[100]; int ir=0; int maxA0=0; int threshold = 0; //Global variables for moving max ^^

//Global Variables for moving average ECG: const int no_averages = 2;

unsigned long time = 0, peak1 = 0, peak2 = 0; int binaryrange, bpm, i=0; //not sure what i does tbh int readings[no_averages]; // the readings from the analog input int readIndex = 0; // the index of the current reading int total = 0; // the running total int average = 0; // the average which we will display as ECG

void setup() { // initialize serial communication with computer: Serial.begin(115200); // initialize all the readings to 0: for (int thisReading = 0; thisReading < no_averages; thisReading++) { readings[thisReading] = 0; }

//set moving max shit to zero for (int is = 0; is < 100; is++) { analogValues[is]=0; } }

void loop() { //int maxA0=0; //Whether I intitate the variables here or globally, same error //int threshold = 0; time = millis();

average=0; readings[readIndex] = analogRead(A0); readIndex++; for (int ir=0; ir < no_averages; ir++) { average = average + readings[ir]; } if (readIndex >= no_averages) { // ...wrap around to the beginning of array if it has hit the end: readIndex = 0; } average = average/no_averages; if (average>1000) { average = 600; } Serial.print(average);

analogValues[ir]=average; ir++; if (ir>=100) { ir=0; } //This is to roll back to the start of the array if it surpasses the 100th array spot for (int is = 0; is < 100; is++) { if (analogValues[is]>analogValues[is-1]) analogValues[is]=maxA0; } }

//**************************

//This line with error:

threshold=maxA0-40;

//**************************

if (average<threshold){ binaryrange=0; } if (average>threshold && binaryrange==0){ peak1=peak2; peak2=time; bpm=60000/(peak2-peak1); binaryrange=1; } Serial.print(" "); Serial.println(bpm); //BPM code ^^

delay(8); // delay in between reads for stability i++; }

THANKS!
