This is driving me mad; hope someone could help me out.

In my index.php I have included my functions.php file which contains all my functions, one of my functions I use a form which includes image validation based on random number, this line that:

Code:
<img src='formmailerV.php' width='60' border='0' height='20' alt='' />

but when i echo my session value it has the previous value!
this is my functions.php

Code:

<div class='form_height'>
<span class='form_left'>Validation: *</span>
<table border='0' cellpadding='0' cellspacing='0'><tr><td><input type='text' name='validate_me' size='6' class='txt_contact'></td><td><img src='formmailerV.php' width='60' border='0' height='20' alt='' />
<label id='body_err' style='visibility:hidden;'>Required Field</label></td></tr></table>
</div>               



formmailerV.php
Code:

<?php

}
?>
