[Passing a variable to the browser to view a record]

Hello there... I'm having trouble with a record update form. I have a repeating table that lists all records in my database and have an arrow image that points to page.php?<?php echo $row_Recordset1['Tag_Number']; ?>

 

However when clicking on this link, The page that displays is the last record entered... not the one with the corresponding Tag_Number I was searching for.

 

I created a record update form called page.php. By opening the page with the ? and the variable shouldn't it open the corresponding page?

 

Any help would be great.
