can't say for sure, but a good guess is some problems with undefined vars.
try using fforeach insted, its alot simpler.
<?php
foreach($check as $j_pos => $j_val)
foreach($check[$j_pos] as $i_pos => $i_val)
$message .= "{$pre[$j_pos][$i_pos]} {$post[$j_pos][$i_pos]}
{$name[$j_pos][$i_pos]} {$city[$j_pos][$i_pos]} {$state[$j_pos][$i_pos]}
\n";
?>
<input type='checkbox' name='check[0][0]' value='1' checked>
<input type='checkbox' name='check[0][1]' value='1'>
<input type='checkbox' name='check[1][0]' value='1' checked>
<input type='checkbox' name='check[1][1]' value='1' checked>
<input type='checkbox' name='check[2][0]' value='1'>
<input type='checkbox' name='check[2][1]' value='1'>
<input type='checkbox' name='check[3][0]' value='1'>
<input type='checkbox' name='check[3][1]' value='1' checked>
ok, now we have an example,
$check[0][0]
$check[1][0]
$check[1][1]
$check[3][1]
are set, the others are not. you can see why 'for($c = 0; $c <
count($check); $c++)' will not work. foreach simplifies things alot. you
also do not need to check
'if ($check[$j][$i] == 1)' becase if it is set at all, then it 'had' to be
checked.
Is this what you were looking for ?
