this code will not add a currency symbol, unless it is in the price column of the data base, this code is just writing the value of the price form the data base to the page, there is no ecart formatting happening on it:
<?php echo $row_rspricetable['price']; ?>
if you want ot use the dcart object settings to format this price us:
<?php echo WA_eCart_DisplayMoney($name, $row_rspricetable['price']); ?>
