I ran into the same problem.

I finished the Review exercise for Intro to Function and received green checks for each step of the review with no issues. However, the program does not run. Instead, I get the following error:

Traceback (most recent call last):
File “travel.py”, line 18, in
trip_planner_welcome(Chris)
NameError: name ‘Chris’ is not defined

Appreciate any feedback or suggestions here.

Welcome to the forums!

The error suggests that the variable Chris was not defined. You should define and instantiate this variable before passing it to a function.
