server to client remote event not transmitting data

[brittle loom]

not gon spend much time on the explanation, want delete effect for specific player, remote event on client not picking up effect.

server:

if delForPlr then serverToClient.deleteFXforPlr:FireClient(plr,sound) end

client:

events.deleteFXforPlr.OnClientEvent:Connect(function(delete)
    print(delete)
    if typeof(delete) == "BasePart" then delete:Destroy()
    else delete = nil end
end)

but it's printing nil.

and no, the sound object isn't nil

when printing on the server it prints Part

and same goes for when im printing the player
