Blueprint linetrace on buttons of a 3d keypad!!

Hello, i have created a bp of a 3d keypad that when firstpersoncharacter collides he can press “e” to interact with the bp and blend firstpersoncam to bp camera and then it turns on the mouse cursor.

After that i want to be able to click on the buttons, so i used a line trace and i setted a collision on every button so the trace gets blocked on the buttons. The problem is that when i try to print the clicked buttons it turns me the string with the name of the blueprint and not of the button i click so i cant move on make a timeline etc…because when i try to animate the buttons it animates the whole bp… any help i stuck here for about a week…
