Smarty

[alez]

Hi!
I have installed Smarty and it seems it works fine.
I have a problem when I pass parameter,for example:

in the file.tpl I wrote

.....<form action= "file.php" method="post">

<input type="text" name="prova" value="{$prova}">
<input type="text" name="ok" value="{$ok}">
<input type="submit" name="submit" value="submit">...

in the file.php I wrote

....echo $prova;
$smarty=new Smarty;
$smarty->assign('prova',$prova);
$smarty->assign('ok','perfect')
$smarty->display('file.tpl');.....

when I give a value (for example "5") to the form "prova" and I press "submit" ,in the next page (that is the same page)
echo prints 5,
in the form "ok" there is "perfect"
but in the form "prova" there is anything.....

It seems that $smarty->assign doesn't work with the same parameter of PHP...
Have I to set anything somewhere?
Thanks!!!
Ciao

maybe you have caching enabled? smarty would display the cached page then.
