I cannot seem to execute it properly...but I did just notice that I skipped a whole section of Java!
:)

2,522 PointsI don't think you are being persnickety. Your correction is correct and taken to heart. I am still getting the error
You should assign the 'status' in the if statement.
I am a little clueless as I missed the whole basics section. I am doing it over.

16,395 PointsOk, this wasn't too hard, although it might be a bit confusing as to what they were asking.
They ask you to declare the variable in the function following best practice, which says to declare variables toward the top of the function, rather than interspersed.
Really the only thing you need to do is declare the status variable right after the function opens, and remove the declaration (not the assignment) from within the if statement.
Let me know if that gets you on track, or if it is still unclear. If so, I can help you further with some pseudo-code for the function. :)

16,395 PointsIn your code above you are declaring and assigning the variable status a value. Don't assign it anything when you declare it (that's not necessarily best practice, just this scenario). After that it should work.

2,522 PointsFinally! Thank you! You were a huge help! Now I am going to go over JavaScript again...from the beginning this time! Thank you!!!

16,395 PointsThat's great to hear! :)
