What can I do to fix "Fix the fields below to continue." It shows up when I go to save an invoice. I end up having to exit and restart and loose my work. How to fix this?

Hey there, @97305autorepair-.

I've checked here on my end and found out that some customers are getting the error message "You have one or more errors. Fix the fields below to continue." when creating an invoice. With this, I recommend reaching out to our QuickBooks Online Support team. They can add to the list of affected users and be able to get updates once there's already a possible fix. 

Here's how to connect with them:

1. From the Search tab, click Contact Us.
2. Enter your question and select Continue.
3. Review and select from the following: Have us call you, or Chat with us.

While our engineers are working on a fix, I'd suggest reviewing your invoice due dates and saving again the invoice. If the Due date section isn't showing, go to the Manage icon and select the Customization drop-down list, then toggle On the Due date button.

Moreover, you can personalize and add specific info to your sales form to help enhance your business communications in QuickBooks. For additional reference, you can check out this article: Customize invoices in QuickBooks Online.
