i have a link from another page to this page.. which is as followed:

<td style=" width :7%;"><div align="right" class="read_icon"><a target="_blank" title="Read" href="test.php?note_id=<?php echo $row2['note_id']; ?>"></a></div></td>

once user click the link, it will open the page (the full source code is copied at my 1st post).. there will be 2 things that this page will do..

1. It will increment the notes table's 'view_count' row to 1..
2. it will read the pdf file..

the 2nd function function well.. but the 1st seems to run twice because each time it is click, the value increment 2 times..

can help to identify where's da error?
