My db won't update with new data in PHP code

Why won't db update with new data in PHP code
 
i am using the attached code.  it just spits out 4 form fields that pull data from db and will update the info if the data is changed in the input boxes.  The first three boxes work just fine.  The fourth box will not update at all unless I go to the db and change the value there.  the value will be pulled into the input box, but if i change the value and click the "change", nothing happens, it will not update the value in that field.
 
<fieldset>
<legend>Update From Emails</legend>
<table class="intake" border="0">
<?
$prjSubmittedTo=getSelectValues('Q_125');
?>
<tr>
 
<td width="25%"><b>Project Submitted to</b>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</td>
<td width="75%"><b>From Email</b></td>
</tr>
 
<?php
$prjSubmittedTo;
foreach ($prjSubmittedTo as $key=>$value)
{?>
<tr>
<td><?=$value?></td>
<td><input type="text" maxlength="50" size="50" name="<?=Field($value)?>" value="<?=getcurrentfromemails(Field($value))?>"></td>
 
</tr> 
<?
}
?>
<tr>
<td>&nbsp;</td>
<td>
<input type="button" onclick="goTo('OPTIONS','emails');" value="Change">
</td>
</tr>
</table>
</fieldset>
