# How much to indent and when should I? Also, keep getting a syntax error on line 10.

print("sorry the tickets are sold out.") Hi I did it this way.. similar to what the instructor showed in the video lecture.

```TICKET_PRICE = 10

tickets_remaining = 100

while tickets_remaining >= 1:
print("The number of tickets remaining: {}".format(tickets_remaining))
user_name= input("Enter your name here:   ")
try:
number_of_tickets=int(input("Hi {}! How many tickets would you like  ".format(user_name)))
if number_of_tickets > tickets_remaining:
raise ValueError("Only {} tickets left. Try again".format(tickets_remaining))
except ValueError as err:
print("Oh no, That is not a valid value. Try again")
print("{}".format(err))
else:
total_amount=(number_of_tickets*TICKET_PRICE)
answer=str.upper(input("Do you want to proceed ? (Y/N) "))
print("Purchase confirmed")
tickets_remaining=tickets_remaining-number_of_tickets
else:
print("{}! Thankyou for visiting our site.".format(user_name))
print("Sorry all tickets are sold!")
```

I indent through using the tab button. On the Treehouse workspace it 2 spaces (shown in the bottom, left). I have just quickly mocked this up. Please follow the videos carefully, I believe you have missed things out. I hope this helps

```TICKET_PRICE = 10

# Prompt the user by name and ask how many tickets they would like

num_tickets = int(num_tickets)
# Calculate the price (number of tickets multiplied by the price) and assign it to a variable
amount_due = num_tickets * TICKET_PRICE
# Output the price to the screen
print("The total due is \${} ".format(amount_due))

should_proceed = input("Do you want to proceed? Y/N ")
