for the catch

that would still fail - unless he has a tag named "this" just like
doing $("a") finds anchor tags. If however he is using "this" in terms
of an event handler (where "this" is a reference to the DOM object that
threw the event, then he would need to remove the quotes:
$(this).siblings('h1').height();
In this case "$(this)" says to put the jquery wrapper object around the
DOM element represented by "this" in the current context.
The difference is very minor, I know, but I did not see in his
description just what "this" represented...

you can't use "this" in same manner as tagnames, ID's or class as a
selector in combination with other selectors the way you are attempting.
try:
h1Height = $('this').siblings('h1').height();

I'm pretty new to Javascript/ jQuery, so this is really bugging me.
I'm trying to get the height of an h1 that is a sibling to this. The
value for the variable h1Height, however, returned as null in the
console in Firebug. Perplexed, I tried console.logging ('this'+'+h1')
to see what it was interpreted as. It brought back this+h1, which
should select an h1 adjacent to this (which is a div).
Javascript
h1Height = $('this'+'h1').height();
What went wrong?
