How to (re)open a window in a frameset

Hi there,
I'm a newby on php and web design, so maybe is my problem very easy to solve
and maybe there is someone out there that can be of any help :-))

What is my problem?
If you click www.deeveedee.net and select Collection from the menu you will
see on the left a list of my collection DVDs.
When you select a genre the list only shows the titles that comply to the
selection criteria. However the page on the right remains unchanged.

The page on the right must show data from the first entry that is shown on
the left.(automatically).
And this i cannot get done!

The code to display the main info on the left is as follows:
for ($i = 0; $i < $rows; $i++)

{ // check for odd/even to set different background colors per row

if ($i%2) {$bckclr="#FFFFFF";} else {$bckclr="#E9E9E9";}

echo "<tr><td align='left' bgcolor=$bckclr bordercolor='#000080'><a
href='col_main_page.php?id=$collection_id[$i]'
target='right'><u>$title[$i]</u></td>";

echo "<td align='right' bgcolor=$bckclr
bordercolor='#000080'>$collection_id[$i]</td></tr>" ;

what i need is a kind of a simulation of a click on the first entry in the
list.

who can help me to solve this LITTLE issue.

Thx in advance,
DeeVeeDee
