I would like to create a ground plane between 2 wires (on the top), i have a layer for the ground and i would like to associate this ground plane on the top to the ground layer.
When i changed the the name of the ground plane (GND) , it dissapears, i thought about a via to change the layer from the top layer.
If you have a GND plane (on which layer?), why do you need another one?
I assume the existing GND plane is a polygon with the according signal name...the same you can do at every layer.

Hi, as you can see on the image there is a red area which is between 2 wires. This area is connected to anything. My GND plane is the third one. I did this to prevent to the crosstalk between the 2 signals.
This is no GND plane. This is just copper pour. It is not connected to anything as far as I can see.
I don´t see a GND plane. You talk about "third one"... What does this mean? A third layer? Then is surely has a number, a name (both should be used to avoid confusion) and can be made visible.

Still unsure what you want to do:
If you want it to be GND, then you need to add any connection.
* This can be a WIRE on the TOP LAYER from any GND signal to this POLYGON.
* or you can use a VIA to get a GND connection from any other LAYER. This via needs to be NAMEd like the GND signal name.
In either case: the POLYGON on the TOP layer needs to have the same NAME as the according signal.

For reducing cross talk you could just draw a WIRE instead of the polygon.
But I doubt that this wire or pologon will result in much improvement with the given layout.
