I'm having an xml-error popping up on a specific part of my tour.

If you go to the bathroom there is a choice on the left to change the materials. If you click on the images of the materials you are supposed to change from one panorama to the other one, but now there is an error popping up when clicking.

I use a node marker to only make this material choice visible on this node. I know it's because of this because before when the node marker was not used and this menu was applied to my whole tour there was no problem at all.

I've attached my settings of the node marker and the image to let you see what is supposed to happen when clicking the image.

Can anyone help me with this?

Thanks!

Or does anyone have an idea on having skin element show up on one node only and not use the node marker?

No one?

Ok so this problem got solved:

I shouldn't have used a tour marker but logic blocks instead: here is the solution from hopki in case someone has the same problem:

"I would not use a node marker.
The two buttons can have a visible logic block that would say when tag = material, visible true.
The each button then opens its relevant node."
