I'm sorry for this but I'm a complete beginner and no matter what I try it's just going wrong. Can anyone give me just a small idea of whats going wrong with my elif statement so I can keep at it? (Also I know there's the current mistake of 1% at the 0%, was just testing the theory)

```
one = (1)
three = (2)
four = (4)
five = (5)
seven = (7)

stampduty = int(input("Enter amount of residential property"))

if stampduty >= 1 and stampduty<=125000:
    add = (stampduty*one/100.0)
    addamount = stampduty + add
    print("Stamp Duty percent 0% \nyour stamp duty amount is", addamount)
elif:
    add =  add = (stampduty*one/100.0)
    addamount = stampduty + add
    print("Stamp Duty percent 0% \nyour stamp duty amount is", addamount)

```
