Amazing ERROR - multiple insert on one CALL

[eluser]Unknown[/eluser]
This thing is amazing... Here we GO!

We call APP/client/run/
in client.php are defs for paths, next load model (cart) - it works.
next - function run() - include of external file (module_cart.php) and init class - it also works.
class Module_Cart calls add() in model... its ok.. and i got informations about added RECORD(one time).
then display template (smarty included).

What is so strange?
"script type="text/javascript" src="{$js}lightbox.js"
because of this line placed in td_news.html (template) record is ADDED 3 times!!!
NO IDEA WHY. time of loading? loop? recursion?
IF I "REM" this line everything is ok!

info from mySQL log:
