prod1q = document.getElementById['prod1q'];
var
prod1p = document.getElementById['prod1p'];
var tab4 = '<?php echo $tab4 ?>';
var tab1 = '<?php echo $tab1 ?>';
var tab2 = '<?php echo $tab2 ?>';
var tab3 = '<?php echo $tab3 ?>';
prod1.src = tab4;
prod1n.setAttribute('src', '#');
prod1n.innerHTML = tab1;
prod1q.innerHTML = tab2;
prod1p.innerHTML = tab3;
}
</script>
<?php }
?>
