**Actual/ observed behavior/ results**

Email address and shares input field validation errors show up at the wrong time in an IA

**Expected behavior**
Valid email error for 'Email Address' or 'Confirm Email Address' input fields
- triggers on blur - when the user selects a different input field AFTER they have entered text into the email address field. Stop Displaying as soon as the user resolves the validation error.

Confirm Email Input Field:
- Display 'Email addresses must match' error only when system detects the email is different than what's entered in the 'Email Address Field'

Share Structure
- only display the 'field is required' errors once the user hit's done button on the add shares form
