Sorry for the subjective question....
I'm working on the micro-copy that appears on a web-form when a user submits invalid data: eg: invalid date/time. We've used inline validation and date time pickers and masks to really try and minimise the risk of invalid data being submitted but we're pretty sure the user is still going to come up with some problems. The app is designed to be used by flight crew, so pilots and air stewardesses and is intentionally a little bit whimsical.... the text I have used so far is:
"Oops, there was a problem with some of the data you entered. Don't worry let's fix that right now"
This is proving a controversial choice as it doesn't seem to be authorative enough, but is in keeping with the micro-copy used in the rest of the app. Combined with this we are highlighting individual fields and telling the user how to fix the individual field istself - this is general alert text which is displayed in the page header Does anyone have any good suggestions or design patterns for better UX?
