Got an upload and submit button within a php contact form, but upon clicking submit for file upload, this submit button submits the whole form, and so does the main submit button. Hence the user cannot upload a file. how can i make sure the file submit does not submit the whole form?
<table width="500" border="0" align="center" cellpadding="0" cellspacing="0" >
<tr>
<tr>
<td>
<!-- start here-->
<form action="contactform.php" method="post">
<table class="freecontact2form" border="0" width="400px">
<tbody>
<tr>
<td colspan="2"><span style="font-size: x-small;"> </span> <br /> <br /></td>
</tr>
