As a matter of good practice, you should include a link to the problem you’re talking about and preferably a link to your own code. If you want to quote actual code in your post, you can put a line with three backticks ``` before and after to show indentation properly.
Quite often if you search for the problem code (here HS08TEST) on the discussion board you will find an editorial that helps for technique and the comments may include some common errors.
I see you’ve sorted out your run-time errors, which were due to receiving two numbers on a line of input (as specified) and trying to convert string to number without splitting, and are conforming to the required bare-bones input/output of the problems here.
Your remaining error is due to not allowing the withdrawal to empty the bank account - zero is a valid final balance.
