extra space at bottom

Hi;
i want to add extra separation between lines when a field has certain
value... right now, i tried bottom padding and Lineheight but none seems to
work...
this is the expression i had on my table detail's line bottom pading :
=iif(fields!UTIL.value="T",10,2)
Any advice?found the problem...
i has to be: =iif(fields!UTIL.value="T","10pt","2pt")
