Micropython on RaspberryPi Pico W Question

[bfpa40]

I'm Using Micropython in Thonny. I have made a script that has my RaspberryPi Pico when powered up set GPIO Pin 13 as an Output then Set GPIO Pin 4 and an Input and then set GPIO Pin 13 high. I now want it to monitor GPIO Pin 14 for an input (High). When receiving the Input High on GPIO Pin14 it will finish the script and start a 10 minute countdown and then set GPIO Pin 13 Low. I think..."think" I have it mostly resolved except for the monitoring pin 14 for the high. I have a while statement calling out monitoring pin 14 with a break statement but not having any luck getting it working correctly. To Trigger pin 14 I have been jumpering pin 36 (3.3vdc) to pin 19 (gpio 14) manually with a jumper wire and i cannot get it to break from the while statement. I have attached the code i have thus far below the line. Again I am using Micropython on a RaspberryPi Pico W. In the shell window on thonny im seeing a "repeating Value is 0" even when jumpering the pin36 to pin 19. can anyone offer assistance?

Thank You! -Brian-

It's hard to tell what's wrong if the indentation is lost. You have to enclose code in lines with three backticks ``` to display it right.
Two comments:
The line p14.value(0) is obsolete. You cannot set the value of an input Pin this way. If the section of the code reads this way:

input = (p14.value())
print("Input Value to Pin 14 is:")
print(input)
print()
while input == 0:
    print("Value is 0")

It will never leave the loop, because you do not update the value of input in the loop. Instead,. it must read something like:

while input == 0:
    print("Value is 0")
    input = p14.value()

P.s.: you can use more that one argument with print, e,.g. print("Input Value to Pin 14 is:", input)

I am trying to post my code with this post, below is the code:

#New Script written in Micropython for Pi Pico

import machine
from machine import Pin

led = machine.Pin("LED", machine.Pin.OUT)
led.off()
led.on()


#Create output for Pin 13
p13 = Pin(13, Pin.OUT)

#Create input for Pin 4
p14 = Pin(14, Pin.IN, Pin.PULL_DOWN)

#Set Pin 13 Value High Initially
Pin(13, mode=Pin.OUT)
p13.value(1)
print("Pin 13 now set high")
#Set Pin 4 Value Low Initially
p14.value(0)

print("Pin 13 is set to:")
print(p13.value())
print()

#To read Pin 13 Value type print(p13.value())


#(Section is for reading Input High on Pin 4)
check = (p14.value())
print(p14.value())
while check != 1:
  check2 = (p14.value())
  print("HELLO")
  if check2 == 1:
      print("Pin 14 went HIGH")
      break
print("HIGH")

x = 0
for y in range(0, 12):
    utime.sleep(1)
    x += 1
    print(x)
    led.toggle()
print()
p13.value(0)
print("Pin 13 is now set Low")
print("Pin 13 is set to:")
print(p13.value())


led.on()
utime.sleep(2)
led.off()
