[SOLVED] Why is there a syntax error in this code? (Python)

Question

Hi I am rather new to coding and I need some help! :) I wrote the following code but it appears to have an error "SyntaxError: invalid syntax" which points to "While InNum>=0:". Can someone tell me where I have gone wrong? My input for InNum was 12. Thank you so much!
InNum = int(input("Key a number less than 20:"))
def Rfunc(Denominator):
While InNum>= 0:
Remainder = InNum%Denominator
print(Remainder)
InNum -= 1
Rfunc(3)
print(InNum)

Answer 1

i see two probs:
while must be lowercase
before while: global InNum

Answer 2

nice!
