After reading the button to delay the execution without stopping action before a

Projects Programming

This is the code I've written probably did not understand well what I had to do, I am newbie

#include <Stepper.h>
#include <AccelStepper.h>
#include <MultiStepper.h>

int buttonPullupPin_0 = 11;
int butonPullupPin_1 = 10;
int val_0 = 0;
int val_1 = 0;

 AccelStepper stepper(AccelStepper::DRIVER, 4, 3);


 void setup()
{  
 pinMode(buttonPullupPin_0, INPUT);  
 pinMode(butonPullupPin_1, INPUT); 
 stepper.setMaxSpeed(100);
 stepper.setSpeed(90);
 stepper.setEnablePin(9); 
 stepper.disableOutputs();
 unsigned long currentTime;
 unsigned long buttonPressedMillis = 0;
}

    void loop()
{
  currentTime = millis();
  val_0 = digitalRead(buttonPullupPin_0);
  val_1 = digitalRead(butonPullupPin_1);
    if (val_0 == HIGH)
    {
      stepper.enableOutputs();   
    }
    
   if (val_1 == LOW)
   {
      stepper.runSpeed();   //I want to continue this action until val_1 == hight plus a certain time delay
 }
    if (val_1 == HIGH) // here i want after reading the button to delay the execution without stopping action before a certain time then execute the action that is conditioned by reading this state of butonPullupPin_1
   { 
      buttonPressedMillis = currentTime;
   }
    if(buttonPressedMillis != 0 && currentTime - buttonPressedMillis >=2000) 
   { 
      stepper.disableOutputs();//I want to delay this action against reading (val_1 == HIGH)
      buttonPresedMillis = 0;
   }
}

AND THIS IS THE ERROR I RECEIVE:
