Looks good but I think it is not quite returning the intended result yet:
http://heartthroblingerie.com/sitemap.php
BTW, changed func_display("customer/home.tpl",$smarty); to func_display("customer/sitemap.tpl",$smarty); but same result (in home.tpl or no) either way.
I did a Save As... and made sure file creator, save state, line breaks and encoding (latin 1) are all unix compatible... no change.
Also, sent small Paypal donation...
Warm regards,
