Changing Dynamic panel and text on next page NOT WORKING! [HELP]

Hey guys i currently got a project about parking cars. I currently have a problem changing the state of a dynamic panel on the next page and also changing the text of two fields.
I have managed to get this to work before but i seem to be stuck.
Would be great another pair of eyes seeing what i do wrong.

So there is two icons a Car icon and a Motorcycle icon. When these gets pressed a value of a variable is assigned and when deselected it should dissapear.
Further it’s possible to pick name and registration number for the selected vehicle.

What i want: the right veichle shown in the dynamic panel on the next page and with the information provided in the fields.
