Hi,
SurveyGizmo doesn’t offer the option to create a separate error message for each page.
Some workarounds: For the login password, put a note that it’s case sensitive.
You can edit your general error message that appears at Edit Survey => Look&Feel.
If you want to gather email addresses, use a textbox and then use Validation (Advanced Edit => Validation). Set the dropdown box to Email Address Format. You can enter your own error message in the text box there. For validation to occur, the question must be required.
I hope this helps,
Cheri
