HMI tags not showing up to be used as source

I’ve followed all tutorials and manuals I could find. And I thought that I checked all the boxes. But I’m either doing something very wrong or encountering a glitch. Because went I set a program or plc tag to be an HMI tag. Nothing happens. Anyone else ran in to this issue?

Please see pictures attached.

If you’re using the built-in Horizontal Gauge symbol, then the GaugeVariable parameter must be of type INT or UINT.

If you change the type of your variable Analog_IN1 to one of these types (and make sure there is an instance of that program in a Task), then you should see this variable in the Horizontal Gauge prarameters window.
You'd think that this would be documented somewhere, but I can't see where, so unfortunately it seems to be trial and error to find the correct data type(s) in this case.

(sorry about the lack of pictures in this forum, this problem is currently with the site admins).
