When I try to run this code

```py
budget = 500
x = 1
y = 1
bet = 0
totalsum = 0
x = input("enter result:")
bet = input("enter bet:")
y = input("you bet on?:")
if x == y:
    bet = (bet) * 2
    totalsum = budget + bet
    budget = totalsum
    print("your winnings:", totalsum)
    print("your budget:", budget)
if x != y:
    totalsum = budget - bet
    budget = totalsum
    print("your winnings:", totalsum)
    print("your budget:", budget)
if budget < 0:
    print("you lost :(")

```

I get a console error:

I don't understand why. Both those values are set to have a numerical value so why is one of them a string? (I think that it what it means by 'str')
