[Typo3] alternative header

[Bart Aninowski]

Hi
This is my alternative header if user select layout4

HeaderFour = TEXT
HeaderFour.wrap  = <div class="bImage"><img 
src="fileadmin/template/main/images/arrow.gif" width="8" 
height="9"></div><div class="header4">|</div>
HeaderFour.field = header

works fine but there is no link
so I try to modify this in this way

HeaderFour = TEXT
HeaderFour.stdWrap  = <div class="bImage"><img 
src="fileadmin/template/main/images/arrow.gif" width="8" 
height="9"></div><div class="header4">|</div>
HeaderFour.stdWrap2.fieldRequired = header_link
HeaderFour.stdWrap2.typolink.parameter.data = field : header_link
HeaderFour.field = header

but it doesnt work
any idea how to do this?
