Hi Dawn,

This quiz seems to be focused on operators such as &&, ||, and '.'

This question's condition has .= which given the 'or' operator in the statement above it '||' means if any of those conditions are true, then echo $error_message will contain a concatenated value for both the text massage values. Hope that helps.
