Suggesting a correction/adjustment to the instructions in the PHP: Parameters lesson.

When I reached the final step (5) I thought I was stumped. Each time I ran my solution it returned incorrect with the comment:

Double check the instructions. It seems like you reversed which function invocation should be passed into which.

I tried swapping the functions and changing how I included the parameters, but nothing worked. I eventually gave up and looked up the solution under “Get Unstuck” - the answer was the first thing I tried!

echo increaseEnthusiasm(repeatThreeTimes("Olé"));

But it still didn’t work!

Finally I tried deleting the echo statement written above it from the previous step (4):

echo repeatThreeTimes("Check"); 

And the step finally registered as correct!

Logically, I can understand why having the previous statement left over was interfering with the results. However, up to now none of the steps in any of the lessons have overlapped like this (unless the questions specifically addressed it), As I had already completed step 4 without any problems, it didn’t occur to me to look outside of my results for step 5 when trying to troubleshoot my answer.

For the sake of clarity I think the question should be adjusted to account for this. Possibly by specifying that step 5 should overwrite step 4, or simply adding some further directions in the hint?

Just a thought. Thank you.
