What am I doing wrong?

In your example, you're asking the user for a number and then you're setting total and nums equal to zero. This results in your first number being ignored by the program. I included the complete working code below:

num = int(input("Enter a number: "))

total = num

nums = 1

while (total <= 100):

   num = int(input("Enter a number: "))

   nums = nums + 1

   total = total + num

print("Sum: "+str(total))

print("Numbers Entered: "+str(nums))

I hope this helps!
