Luke, Your question's format stressed me to the core. You should definitely learn to use format properly, start by watching this.

I'm not sure why you would be expecting such a warning, since there's nothing in this code that would test for a limit on the price. I guess you can charge whatever you want! :see_no_evil:

I'm trying to raising a value error when the number of tickets exceed 100. When I type a number over 100 tickets, it treats it like it isn't too much:

"The total is due $....... Do you want to proceed Y/N?" Then it says to the user that the tickets it's SOLD, and it's out of tickets.

This might be the result of an indentation issue, but we can't check it in unformatted code. Try editing the code part of the question using Markdown formatting to preserve the original appearance.

Thanks for both of your response. I will look into it that very soon. Thankfully, I retyped the whole lesson, from reviewing another person's attempt,(with a couple of different variable name changes and values) and it works perfectly now.
