different header for different signup pages

i have a signup page group 8
i want that signup page to have a different header and footer

any idea what to add in the header and footer . i know its possible just forgot how to do it

Something like:
{if {$smarty.request.price_group eq "1"}
{include file="header.html"}
{else}
{include file="header2.html"}
{/if}

thx alot

with the above i get the following error:

ERROR [256] Smarty error: [in signup.html line 2]: syntax error: $smarty. is an unknown reference (Smarty_Compiler.class.php, line 2031) in line 1102 of file /home/kevin3434/public_html/member/smarty/Smarty.class.php

{if {$smarty.request.price_group eq "1"}

should be
{if $smarty.request.price_group eq "1"}
