Hi shadiadi,
Welcome to the forums. In the future, please post in newbies, untill you are more comfortable with PhP. It will help you get more elaborate responses.
The easiest way to do this is by passing the identifier value (intnewsID) through the link, instead of using some javascript to process a hidden form:
echo "<a href=\"news.php?itemdid=".$tradeaid."\">".$stitle."</a>";
Also, you do not need to get the variables from the $row[] array: You can just use those values directly:
echo "<a href=\"news.php?itemdid=".$row['intAccountID']."\">".$row['newsshTit']."</a>";
For some more explanation on passing variables by the url, visit the coding examples (link bvelow)
