Title, pretty simple:
-- LocalScript
game.ReplicatedStorage.RemoteEvent:FireServer(cframe)
And the other script,
-- Script controlling RemoteEvent
part.CFrame = cframe
But of course Roblox in the Output is like 'CFrame is not vaild member of Player'
This should be straightfoward, does anyone have a fix? Thanks.

We need more information on the scripts so we will understand.
Well the studios rules say I can't leak too much information on scripts, the only thing I can say is that it is for an FPS.
without your script and your problem, we cant do anything about it
