You still have the original recordset as well as the mysqli version and they share the same name.... the page should just be:
<?php require_once('../Connections/biznew.php'); ?>
<?php require_once('../webassist/mysqli/rsobj.php'); ?>
$RecordsetLi = new WA_MySQLi_RS("RecordsetLi",$biznew,1);
$RecordsetLi->setQuery("SELECT * FROM newpc");
Then you can apply the mysqli repeat region on the page and it should all work properly.
