this works, you should be able to do something similar assigning
$row["checkboxtype"] as the array key. That way you don't need to know what
it's called just the array it is an element of.
<?php
if (isset($formvars))
{ foreach ($formvars as $fvTitle => $fvValue)
echo("$fvTitle:$fvValue<br>");
};
?>
<form action="#" method="post">
<?php
$gotvars[fred] = "fred value";
$gotvars[bill] = "billvalue";
foreach ($gotvars as $gvTitle => $gvValue)
echo("$gvTitle<input type=text name=formvars[$gvTitle] size=40
maxlength=80 value='" . $gvValue . "'><br>");
?>
<input type="submit" value="GO">
</form>
