When I add a user and answer all the questions, when I go to save the button is grayed out and will not save. What am I doing wrong?

Let me help you to add a user in QuickBooks, @wfwinters. 

If this the case, I'll recommend performing some troubleshooting steps to void this out.

The first thing to do is open QuickBooks using InPrivate or incognito mode. This feature doesn't use the existing webpage cache data which can cause unusual behavior in QuickBooks Online.

Here's how to open:

• Press Ctrl + Shift + N (Google Chrome).
• Ctrl + Shift + P (Firefox or Internet Explorer).
• Control + Option + P (Safari).

Once the private browsing opens, try to add the user again. If you can add a user successfully, clear the cache of your normal browser to start on a clean slate.

Keep us posted on the result. We'll be right here if you need our assistance.
