You need quotes around your insert values

while($info=mysql_fetch_Array($data))
{
    print "name :".$info['Id']." ";
    $count=$info['Id'];
}

$t="INSERT INTO Table_Faces(Id_Obj,Num_Sides)VALUES(";
$t = $t."'IdObj$count'".",'".$_GET["ns"]."'";
$t = $t.")";
mysql_query($t);

ie INSERT INTO Table_Faces (Id_Obj, Num_Sides) VALUES('asdf','foo')

I also recommend you use mysql_real_escape_string on all of the variables you are inserting in a table to avoid SQL injection attacks.

The problem is the values in your query should be quoted. Try this:

$t='INSERT INTO Table_Faces(Id_Obj,Num_Sides)VALUES(';
$t .= '"IdObj' . $count . '", "' . $_GET["ns"] . '")';
mysql_query($t);

Note that you are explicitly pasting an $_GET[] variable into your query, which is a direct security issue, everybody who has the URL can use SQL injection.

Are you trying to create a new field called Id_Obj4 in the table Table_Faces or are you trying to add a value of Id_Obj4 into the field Id_Obj?

Try

$t  = 'INSERT INTO Table_Faces (Id_Obj, Num_Sides) VALUES ';
$t .= '("IdObj' . $count . '", "' . $_GET['ns'] . '")';

Note that there's a massive potential for Bobby Tables errors right there.
