            return cell;         }     }     return nil; } -(ratingcell *)getratingcell { nsarray *toplevelobjects = [[nsbundle mainbundle] loadnibnamed:@"ratingcell" owner:nil options:nil];     ratingcell  *cell;

your table view cells being reused. way table view cells being optimized.

if know how many sections , rows table view has , not change, consider using static table view cells suitable forms:

http://developer.apple.com/library/ios/#documentation/userexperience/conceptual/tableview_iphone/tableviewcells/tableviewcells.html

look @ section the technique static row content.

otherwise need save value of each text field variable, such rating, email, description, , put text field every time respective table view cell loaded.
