<?

    echo "<form name='form1' method='post' action=''>";

while($objResult = mysql_fetch_array($objQuery))
{


    echo "<tr>";
    echo "<td align='center'><input name=\"checkbox[]\" type=\"checkbox\" id=\"checkbox[]\" value=\"$objResult[addedrec_ID]\"></td>";
    echo "<td>$objResult[addedrec_ID] </td>";
    echo "<td>$objResult[FirstName]</td>";
    echo "<td>$objResult[LastName] </td>";
    echo "<td>$objResult[MobileCompany] </td>";
    echo "<td>$objResult[Cell] </td>";
    echo "<td>$objResult[WorkPhone] </td>";
    echo "<td>$objResult[Custgroup] </td>";

   echo "</tr>";

}


echo "<td colspan='7' align='center'><input name=\"delete\" type=\"submit\" id=\"delete\" value=\"Delete\">";

if (isset($_POST['delete']) && isset($_POST['checkbox'])) // from button name="delete"
{
$checkbox = ($_POST['checkbox']); //from name="checkbox[]"
     $countCheck = count($_POST['checkbox']);

for($d=0;$d<$countCheck;$d++)
     {
         $del_id  = $checkbox[$d];

$sql = "DELETE from UserAddedRecord where addedrec_ID = $del_id";

$result2=mysql_query($sql)  or trigger_error(mysql_error());;;

     }
         if($result2)
     {  
          $fgmembersite->GetSelfScript();
         }
         else
         {
echo "Error: ".mysql_error();
         }
}

Check out this sample form.

if (isset($_POST['delete'])) // from button name="delete"
{
foreach($_POST as $key => $value){
IF ($key!="delete"){
//mysql_query("DELETE FROM UserAddedRecord WHERE addedrec_ID=$key");
echo "Item $key was removed<br />";
	}
}
}
?>

Keep in mind that <form> tags should not go around <tr> or <td> tags.  Only around whole table or inside a cell (<td></td>).

Form names and id's need to be unique.  By using the record id as the name, the name will be unique and you can easily process a foreach statement as each posted value equals the $key.  Just be sure to filter out any other posted values like "submit", which is why I added the IF statement.
