Hi all,

I have been trying to add a new tab to my Tier 2 Navigation Tab. I was able to add it to the top-level tabs, but when I try to configure the Tier 2 navigation, the subtabs that are supposed to appear when I click the main tab are not showing.

Instead, the screen is grayed out, and I can still see the subtabs from the previously selected main window. It also shows what looks like a tag icon with a red “X” in the top left corner of the screen.

I watched the training videos and I think I am following the correct steps, but I must be missing something.

Please see the screenshot below. The new main tab I added is called "Central", and the subtab is called "Hooder", which I created as a Main Window.

Does anyone have an idea of what I could be doing wrong?

Thanks in advance for your help.

In general that icon means that ignition can't find the tag/property that you are attempting to bind to. Double check the bindings on the 2nd tier tab(s) and make sure the property or tag that they have bindings to actually exist.

If you were following the video the binding to check would be on the `visible` property of the tabs.
