NVDA/IE does not read the numbers to me Bryan.
Firefox and Chrome/NVDA does though.

Why are you including aria-live and aria-atomic in combination with role=alert? The alert role includes all supporting attributes automatically and combining it with others may conflict with the role.

I just tested this using NVDA in Firefox on Win7 with role=alert as documented here, and it works as expected.

The test page referenced in this section includes a Test button for validating this functionality.

Also, live regions should not be nested. The JS method being used to add content to the container may also yield differing results as well.

Yes ... I've tried that already. No difference, but I'll update it to the correct way.

Hi Greg,

The "alert" role should be on the live container, not the message.

<div class="text-center" role="alert" aria-live="assertive"
aria-atomic="true">
<asp:Literal runat="server"></asp:Literal> </div>
