[TYPO3] templavoila FCE "header" field

[Surer Dink]

All,

Can someone please tell me (or better yet, point me at a reference
where I can look it up) how to get the value of the current FCE's
"header" field in templavoila?  Part of the template contains an
<h2>insert-header-here</h2> , and I would like to take the "header"
field which can be set for every content element and map the value
into this <h2>.

Thanks!
