Issue with php/mysql inserting entry with checkbox checked into database - php

Question

Below is the code from catalog page with the data which has to be inserted to the database. It has some problem and i cant insert that data to the database table, and i think i have not ported variables correctly.
My catalogue page has this code (it is for purchasing photographs):
while ($row=mysql_fetch_assoc($result))
{
echo "<tr><td width=100><img src=".$row['FilePath']." /></td>";
echo "<td width=100 padding=25>".$row['Title']."</td>"; $hour = time() + 3600; setcookie('titlecookie', $row['Title'], $hour);
echo "<td width=100 padding=25>".$row['Cost']."</td>";
echo "<td width=100>".$row['FileSize']."</td>";
echo "<td width=100>".$row['CaptureDate']."</td>";
echo "<td width=100>".$row['Resolution']."</td>";
echo "<td width=100><input type=checkbox name=checked[] value=select />Purchase</td></tr>";
}
echo "</table><input type=submit name=submit value=Purchase></form></center>";
}
else
{
echo "Query not successful";
}
The code for my purchase page appears as follows:
$username = "COOKIE['ID_my_site']";
$title = "COOKIE['titlecookie']";
$Custid = mysql_query("SELECT Custid from Customer Where Username=$username");
$Money = $_POST['Cost'];
$Photoid = mysql_query("SELECT Photoid from Photograph Where Title = $row[Title]");
foreach ($_POST['checked'] as $select) {
if(mysql_query('INSERT INTO Transaction (Money, Custid)
VALUES ($Money, $Custid)'))
{
echo "successfully added to Transaction";
}
else
{
echo "Problems adding data to Transaction";
}
if(mysql_query("INSERT INTO TransPhoto (Photoid, Transid)
VALUES ('$Photoid', '$Transid')"))
{
echo "successfully added to Transphoto";
}
else
{
echo "Problems adding data to Transphoto";
}
}
Could you possible assist me with fixing this code? I am relatively new to this but have searched and could not find an effective solution. Thanks
