Mails aren't going to addresses because of switch/field control (Multiple form)

[manyakabi]

I have a multiple form mail script. I want mails to go addresses in mail.txt. However, mails successfully go first 5 address in mail.txt but later it says "please write your name". How can I fix this problem? Thanks a lot...

FORM FILE (form.php)

<form action="/staticfiles/send.php" method="post" target="_blank"><br>
<table border="0" summary="">
<tr>
<td>
Name:
</td>
<td>
<input type=text style="width: 250px" name="adsoyad" size="40" maxlength="256"><br>
</td>
</tr>

<tr>
<td>
E-mail:
</td>
<td>
<input type=text style="width: 250px" name="kimden" size="40" maxlength="256"><br>
</td>
</tr>

<tr>
<td>
Subject:
</td>
<td>
<input type=text style="width: 250px" name="konu" size="40" maxlength="256"><br>
</td>
</tr>

<tr>
<td>
Message:
</td>
<td>
<textarea style="width: 250px; height: 150px" name="mesaj" rows=13 cols=65></textarea><br>
</td>
</tr>
<tr>
<td>
</td>
<td>
<input style="width: 125px" type=submit value="Send">
</td>
</tr>
</table>
</form><br>
