I'm writing a javascript function that is supposed to open and close a box
by adjusting the height style of a div container, everytime the link is
clicked. For some reason though, the function only works once--I click and
it opens, and then I click again and it closes--then it never does it again.
Why doesn't it do it again? I plan to have multiple div containers on the
page that do the same thing, but for some reason they stop after the first
close. Help would be appreciated--thanks.
