Syntax error on line 23 for except statement

I was wondering if you could help explain why I keep getting the SyntaxError: invalid syntax on line 23 (the "except ValueError as err" line)? I keep re-typing it in thinking there is a spacing issue/typo, but I can't seem to figure out what is triggering the error. I saw a similar question pertaining to this, but I thought I had fixed the indentation issue?

Edit: Thank you, Steven! Now I can post the example.

while tickets_remaining >= 1:
    print("There are {} tickets remaining.".format(tickets_remaining))
    name = input("What is your name?  ")
    num_tickets = input("How many tickets would you like,  {}?  ".format(name))
    # Expect a ValueError to happen and handle it appropriately... remember to test it out!
    try:
        num_tickets = int(num_tickets)
        if num_tickets > tickets_remaining:
            raise ValueError("There are only {} tickets remaining."(format(tickets_remaining))
    except ValueError as err:
        print("Oh no, we ran into an issue. {}. Please try again.".format(err))
    else:
        amount_due = calculate_price(num_tickets)
        print("Your total will be ${}.".format(amount_due))
        interested = input("Would you like to proceed with your purchase?\nEnter (Y/N)  ")
        if interested.lower() == "y":
            # TODO: Gather credit card information and process it.
            print("SOLD!")
            tickets_remaining -= num_tickets
        else:
            print("Thank you anyway, {}!".format(name))
print("So sorry, {}, but there are no tickets remaining.".format(name))

Hey there Natalie Heyde ! I took a look at your snapshot. Sometimes if you don't see an error on the line that it says, it could be something in the line above it. In line 22 there is a missing closing parenthesis on your raise ValueError(). This happens all the time, but if you ever get stuck, try checking out the line about the error.
