Javascript not working as expected, why?

Question

Hi,

I have javascript to set equal column heights of two divs contained by a parent div. Somebody even coded an working example that works (mine doesn't). What I have found is that it IS setting the height of the container which contains the two divs I intended to set. Why is my script setting the container height rather than it's children? Please see my previous question at:

What does the following line actually do? I don't understand the "> div" part.

setEqualHeight($(".instructionsParent > div"));

Answer 1

parent > child

"Matches all child elements specified by "child" of elements specified by "parent"."

Answer 2

The selector ".instructionsParent > div" means "select all the div elements that are children under the element with the class instructionsParent". So the div elements are the elements selected here.
