Code Igniter / PHP - Undefined index? Easy points for someone

[brice07]

This is probably obvious but I'm getting this error:\[code\]A PHP Error was encounteredSeverity: NoticeMessage: Undefined index: outputcardsFilename: controllers/site.phpLine Number: 49\[/code\]Here's the line in question:\[code\]$out['outputcards'] .= $this->load->view('client_view_data',$data, TRUE);\[/code\]which is inside a for loop, and being used in the view as echo $outputcards.All works fine, but the error is there at the top.Any ideas?Thank you!
