SyntaxError: Invalid Syntax

This is my code

TICKET_PRICE = 10

tickets_remaining = 100  




while tickets_remaining >= 1:

  name = input("What is your name? ")
  print("Welcome {}!".format(name))
  print("There are {} tickets remaining.".format(tickets_remaining))

  try:
    order_amount = int(input("How many of those would you like," + name + "? "))
    if order_amount > tickets_remaining:
        raise ValueError ("Sorry  there are only {} tickets left".format(tickets_remaining)   
  except ValueError as err:
    print("Sorry, we ran into an issure. Please try again. {}.".format(err))

    else:
      order_price = order_amount*TICKET_PRICE

      print ("That comes up to $", order_price)

      ask_proceed = input("Do you want to proceed?    Y/N ")
      if ask_proceed.lower() == "y":
        print("SOLD!!! Have fun " + name)
        tickets_remaining -= order_amount

      else:
        print("Thank you anyways {} and have a nice day".format(name))

print("Sorry that's all folks!! ")

I get a Syntax Error pointing to the e in except and I have no idea what is wrong, try and except ar indetned the same amount so that can't be it

When something needed is left off, the error often points to the next character after the problem.

In this case, the parentheses on the previous line are unbalanced (the function still needs a closing parenthesis).

The "else" is indented too far and doesn't line up with the "try" and "except".
