Gui still showing even though it shouldn't?

So, I'm making a katana have an ability and when you press e it will sort of slice through the player. I made it so a gui shows as well to show whats happening, sort of like a flash. Anyways, when I use it on a player it works fine, but for an npc, since its not a player the playergui won't work, but even though I put an if statement saying if the name of it is equal to so and so, it still goes through with the script even if the name of the npc is listed on there. Help would be appreciated!

Here is the script in serverscript service which gets activated when a remote gets fired.

sword.Handle.Hitbox.Touched:Connect(function(hit)
		if hit.Parent:FindFirstChild("Humanoid") then
