						if(!$_GET["Page"]) 
							$Page = 1; 
							$Prev_Page = $Page - 1; 
							$Next_Page = $Page + 1;
							$Page_start = ($Per_Page * $Page) - $Per_Page; 
					
							if($result <= $Per_Page)
								$Num_Pages = 1; 
						
							else if(($result % $Per_Page) == 0)
								$Num_Pages = ($result / $Per_Page); 
					
						else
