While loop-repeats for as long as the specified conditions are true

What would this print? Is there a bug? What is the bug?
x=23
y=75
if x<=22:
if x<=23 and y>= 75:
print("ok")
else:
print("no")
elif x>=23 or y>= 75:
if not(x <= 23):
print("stop")
if not(x <= 22) and not(y <= 22):
print("this seems right")
elif (x >= 14):
print("confused?")
else
print("im done")
else:
print(4)
this seems right
colon missing in last else statement
