On your details page create a recordset with the data you want to display. If you click on test in the recordset it should display all the records.
Go to the simple display and in the "filter" dropdown select the unique identifier (usually ID).
Make sure URL parameter is selected. This should auto populate the box next to url parameter with "ID". Please note that I'm just guessing "ID" it's what ever you called the auto increment column of your database. Click OK and close this dialog box
Bind whatever fields you need to the page so it displays your "details".
Go to your results page and highlight some text in the row (or create a "Details" link). Link this to the details page.
Now the tricky bit. Suppose this link is "details.php" you need to add "?id=" and then bind the ID from the recordset on that page so it will look like:
details.phpID=<?php echo $row_rsRecordset['ID']; ?>
Now, if you display the results page in your browser and click on the link it should go to the details page taking the url parameter of the record with it. This will then call the correct record and display it on the page.
Edit: Ooops, looks like Jason beat me to it :)
