I have been into the booking form for this client and changed the colour of the Required text color to blue but it is showing white.
See screenshot
Also as the client has an email address that isnt the domain, i.e. a bigpond email..I have gone and added the following text in the from field .. {default_from_email_address} See screenshot
You can set a different “From” address for each email that is sent by going to Edit Form → Settings → Notifications, then going to the notification settings then to the “From” address field. The global option Default “From” on the Forms → Settings page will only have an affect if inside the notification settings the “From” address is set to {default_from_email_address}.
