this test suite is broken. All the tests try to submit variables into the function that have not been declared yet. i.e. the first assertion is submitting x14 and y14 that are declared 16 lines later.

Thanks Andrew. I should have test-solved it but I didn't want to be the first. I'll gladly fix it.
Best, Jerry

Andrew, thx again. I had pasted the self-checkers into the test suite in the incorrect order...

Jerry, you can test your solution against the test suite before posting the problem. On the edit page for the problem, there is space for a reference solution at the bottom along with a button to test the reference solution. It is good practice to include a reference function for each created problem to ensure that the test suite is solvable.

Hi @goc3.
Thanks for the advice - that's my first posted problem!
