Consider:

while ($j < $num2) {
$parent_id=mysql_result($result2,$j,"parent_id");
$fam_first_name=mysql_result($result2,$j,"fam_firs t_name");
$fam_age=mysql_result($result2,$j,"fam_age");
echo "it is $parent_id";
echo "<tr id=$parent_id>";
echo "<td></td>";
echo "<td >$fam_first_name</td>";
echo "<td>$fam_age</td>";
echo "</tr>";
++$j;
}

The line that says "it is $parent_id" will print the variable.
The next parent id will skip one if it has two of the same values. I
know this may not make sense, but:

it is 1
it is 3
it is 3
it is 6


but the second three from above will never be in the tr id= tag. i
hope this makes sens. It just doesn't print in the tag if it has two
rows.
thanks.

Maybe you have something extra in $parent_id.

Do
<?php
echo "<pre>it is [$parent_id]</pre>";
?>

to verify that.

In your browser the string "it is 3" (notice *two* spaces)
is shown as "it is 3" (notice *one* space)


Happy bug hunting :-)

Thanks. Actually, I found that I had to separate the string on three
different lines:

so, for example:

echo "<td id=";
echo $parent_id;
echo ">";

then it would print. Bizarre. I used to run into these quirks with
ASP (classic) too.

Cleaner and faster to write would be just to do
echo "<td id=" . $parent_id . ">";

Or even for more performance (although not noticeable):
echo '<td id=' . $parent_id . '>';

And finally, to avoid html-problems if the $parent_id happens to contain
spaces (you never can be too sure), do:

echo '<td id="' . $parent_id . '">';

As what html concerns, values of an attribute must be put between " " or
' '. Thus <td id='value'> is valid too.


Oh and the last option echo "<td id='{$parent_id}'/>";
