Email template, print if certain OS template is selected

Hello,

in product welcome email, i want to display speciffic information if client choose certain configurable option (OS template)

example he chooses one with Kloxo control panel so i want to send client speciffic info about Kloxo.

i tried:

{if $configurable_option eq "centos-5-x86_64-lamp-kloxo|centos-5-x86_64 - Linux Apache MySQL PHP + Kloxo"}Kloxo details{/if}

but this dont show anything, what is the proper IF code to use?
I see these config options are in mysql table tblproductconfigoptionssub , not in tblproductconfigoptions
