Problemas sérios com POST

Caros amigos,

estou a 4 dias com este erro e não consigo resolver.

Tenho uma página que envia 30 campos via form...

Mas não consigo receber os valores de 10 campos (campos que começam com nt_aplicar1, nt_aplicar2.... nt_aplicar10)

Não encontrei nenhum erro no código! Estou perdido

Abaixo segue o codigo do form:

<form action="v_regua.php" method="post" enctype="application/x-www-form-urlencoded" name="i_regua" id="i_regua" ><?php require "cabec.php"; ?><table width="760" height="295" border="0" align="center" cellpadding="0" cellspacing="0" bgcolor="#FFFFFF" class="bordalateral">  <!--DWLayoutTable-->  <tr>    <td width="10" height="10"></td>    <td width="136"></td>    <td width="10"></td>    <td width="576"></td>    <td width="29"></td>  </tr>  <tr>    <td width="10" height="35"></td>    <td rowspan="2" valign="top"></td>    <td width="10"></td>    <td align="left" valign="middle">      <span class="style12"><span class="style13">Régua de Nota</span><br>Cadastramento de Régua de Nota </span></td>    <td></td>  </tr>  <tr>    <td width="10" height="241"></td>    <td width="10"> </td>    <td valign="top"><table width="100%" border="0" cellpadding="0" cellspacing="0">          <!--DWLayoutTable-->          <tr>            <td height="38" colspan="6" valign="top"><span class="textoform">Nome</span><br>              <input name="nome" type="text" class="textbox" id="nome" value="<? echo $nome ?>" size="90" maxlength="100"></td>          </tr>          <tr valign="middle">            <td width="21" height="22"></td>            <td width="122" align="center" valign="bottom"><span class="textoform style16">Nota Inicial </span></td>            <td width="120" align="center" valign="bottom"><span class="textoform style16">Nota Final </span></td>            <td width="134" align="center" valign="bottom"><span class="textoform style16">Nota a aplicar </span></td>            <td width="148"></td>            <td width="30"></td>          </tr><?  $idx = 1; $idx2=2; $idx3=3;    while ($idx<=10){ ?>          <tr valign="middle">            <td height="25" align="center" valign="middle"><span class="style15"><? echo $idx; ?> </span></td>            <td align="center" valign="middle"><input name="nt_ini<? echo $idx; ?>" type="text" class="textbox" id="nt_ini<? echo $idx; ?>" value="<? echo $notaini[$idx]; ?>" size="13" readonly="true"></td>            <td align="center" valign="middle"><input name="nt_fim<? echo $idx; ?>" type="text" class="textbox" id="nt_fim<? echo $idx; ?>" onBlur="javascript:calcula(<? echo $idx2 ?>)" value="<? echo $notafim[$idx]; ?>" size="13" maxlength="7"></td>            <td align="center" valign="middle"><input name="nt_aplicar<? echo $idx; ?>" type="text" class="textbox" id="nt_aplicar<? echo $idx; ?>" onBlur="javascript:validanota(<? echo $idx3 ?>)" value="<? echo $notaaplicar[$idx]; ?>" size="13" maxlength="5"></td>            <td></td>            <td></td>          </tr>          <? $idx++; $idx2=$idx2+3; $idx3=$idx3+3;} ?>          <tr align="center" valign="middle">            <td height="22"  colspan="5" valign="middle"><input name="btn_submit" type="submit" class="botao" id="btn_submit" value="Inserir"></td>          <td> </td>          </tr>          <tr align="center" valign="middle">            <td> </td>            <td> </td>            <td> </td>            <td> </td>            <td> </td>            <td> </td>          </tr>           </table></td>    <td></td>  </tr>  <tr>    <td></td>    <td></td>    <td> </td>    <td valign="top"><!--DWLayoutEmptyCell--> </td>    <td> </td>  </tr></table></form>

E o código da página que recebe é este:
