It is better to use ',' to represent a list of values, it should be a quick fix since all other functionalities are working, please remember to trim after split(',') since users could add spaces after comma

for value in quartervalueList:
driver = webdriver.Chrome(ChromeDriverManager().install())
login_myportal(driver)
# Wait for the 'list-group-item' can be found and clicked
web_driver_counter = 400
