Front end login issue

it doesn't work

I have websites on two version Joomla 3.2.3 and 3.3
. I use the same component on both websites
In frontend when I make FormComponent, the main button SEND gives no effect - dont save item
But if I put not correct value in input field the SEND button work - that monit, that I set wrong value

I noticed - when I logged as superuser in frontend - it works. But every user have to be superuser?

Of course I set all permissions for registered user in backend component administration

this code (in views/form) has an some error - when I remove that - it works for registered user too:

<?php if (!JFactory::getUser()->authorise('core.admin','lista')): ?>
<script type="text/javascript">
jQuery.noConflict();
jQuery('.tab-pane select').each(function(){
var option_selected = jQuery(this).find(':selected');
var input = document.createElement("input");
input.setAttribute("type", "hidden");
input.setAttribute("name", jQuery(this).attr('name'));
input.setAttribute("value", option_selected.val());
document.getElementById("form-kontakt").appendChild(input);
jQuery(this).attr('disabled',true);
});
</script>
<?php endif; ?>

Thanks for the suggestions....
