Добавить доп цену в php

Всем добрый вечер, есть скрипт самописанного движка, пытаюсь вывести поле с мускуля но безрезультатно. Подскажите спецы как же его вывести...

сам скрипт с которого вводятся данные с админки (цена, старая цена артикул...)

и при попытке вставить доп поле не срабатывает

echo "<td class=\"fr\" align=\"center\"><input type=\"text\" name=\"prvals2[]\" class=\"txtprice\" value=\"".$price3."\" /></td>";

в бд таблица price3 создана

вставляю вывод доп цены сразу после ( echo "<td class=\"fr\" align=\"center\"><input type=\"text\" name=\"prvals2[]\" class=\"txtprice\" value=\"".$price2."\" /></td>";)
