Wrox - Beginning PHP4 Ch12 example problem

Happy Easter to all! In the user viewer example at the end of Chapter 12 - has anyone had problems with the source downloaded from their website? The story so far with my trials of this example: downloaded source created table in mysql and populated it (with the SQL script provided) First page ie function list_records() works 'fine'. Except a javascript error at the foot of the page - page done, with errors. Sorting hyperlinks all work, as does all the forward, reverse paging. What doesn't work is the function view_record() hyperlinks. I believe things are going awry in javascript (of which I know nothing, and have the dummies guide in front of me) as it doesn't get to opening a new window. I've tried calling the function as follows: <a href="javascript:open_window('www.google.com');">Google</a> No joy at all - javascript error. <SCRIPT LANGUAGE="JavaScript" TYPE="text/javascript"> <!-- function open_window(url) { var NEW_WIN = null; NEW_WIN = window.open ("", "RecordViewer", "toolbar=no,width="+ <?php echo $new_win_width ?>+ ",height="+<?php echo $new_win_height?>+ ",directories=no,status=no, scrollbars=yes,resize=no,menubar=no"); NEW_WIN.location.href = url; } //--> </SCRIPT> Any help greatly received. Grrrrrrr I'm trying to learn php, not hack javascript... David Mateer. dave@interlynx.co.uk
