My multiple-part keycard doesn't work, what should I do? (w/scripts - read desc)

I am trying to union all the parts to make a handle, or for some reason, it makes some of the text parts either black or it makes everything transparent. I want the username script to still work (which is inside one of the textbox scripts). If I don't do it, only the part named "Handle" will stay in my hand and everything else on the ground. What do I do?

EDIT- The script is for a local nametag on the keycard. Card (Tool) > Nametag > SurfaceGui > TextBox > LocalScript

LocalScript:

local player = game.Players.LocalPlayer

local text = script.Parent.Text

text = ""..player.Username
