CS50P Problem Set 5 - Back to the Bank

Dear participants,

I need help and decided to ask you what is the best place to get it.

I am taking David Malan's CS50P course. I got up to Problem Set 5 and I am stuck at the "Back to the Bank" problem.

I created the required Python script and run it flawlessly. However, when I checked the script with "check50" I got the following error:

:( test_bank catches bank.py without case-insensitivity
expected exit code 1, not 0
Unquote

Would someone kindly indicate where I could get help?

Thanks
