[QUOTE="Mark FX, post: 1585831, member: 211556"] Secondly you will have to access your subtotaalLbl like this. [CODE] [self subtotaalLbl setText: [NSString stringWithFormat:@"%.2f", subtotaal]]; [/CODE] Unless your going to synthesise the IBOutlet property of your label like this. [CODE] @implementation ViewController @synthesize subtotaalLbl; [/CODE] Then you can access the subtotaalLbl in your original way like this. [CODE] [subtotaalLbl setText: [NSString stringWithFormat:@"%.2f", subtotaal]]; [/CODE] The alternative if you don't want to synthesise the IBOutlet property, is to refer to the subtotaalLbl like this. [CODE] [_subtotaalLbl setText: [NSString stringWithFormat:@"%.2f", subtotaal]]; [/CODE] I think this is where the error message you posted is coming from. Regards Mark [/QUOTE]
