How to resolve invalid syntax issue? : <p>I have this issue and can't seem to find a resolution to it. It keeps showing me on line 15 invalid syntax. What's wrong with it?</p>

<pre><code>print("Shirt Order")
print()

colour = input("What colour of the shirt? Blue or White: ")
if colour.lower() == "blue":
    size = input("What size of the shirt? (S/M/L): ")
    if size.lower() == "l":
        print("Sorry, we do not have that size available.")
elif size.lower() == "m":
    print("You have selected a blue shirt in size medium, that will be $9 please.")
elif size.lower() == "s":
    print("You have selected a blue shirt in size small, that will be $5.50 please.")
else:
    print("Sorry, your order was not recognized, please try again.")
elif colour.lower() == "white":
    size = input("What size of the shirt? (S/M/L): ")
    if size.lower() == "l":
        print("You have selected a white shirt in size large, that will be $10 please.")
elif size.lower() == "m":
    print("You have selected a white shirt in size medium, that will be $9 please.")
elif size.lower() == "s":
    print("Sorry, we do not have that size available.")
else:
    print("Sorry, your order was not recognized, please try again.")
