Code: Select all
//set variables to check appropriate radio buttons
if ($rowїnews] == 1) {

$news_last = "checked";
}
else {
$news_last = "";

echo "<td><font class='small'>Display news items:</font></td>";
echo "<td><font class='small'>Random<input type='radio' name='news' value='1'$news_rand> Last Entered<input type='radio' name='news' value='2'$news_last></font></td>";
