Hopperbin connecting script?

bin = script.Parent
owner = hit.OwnerName
function onButton1Down(mouse)
local hit = mouse.Target

if hit == nil then return end
if hit.ClassName == "Part" and
    owner.Value == script.Parent.Parent.Parent.Name then
    hit.ClassName.Locked = false
    else
    hit.ClassName.Locked = true
end
end

I have a hopperbin at starterpack this drags a part, and the part have stringvalue name OwnerName with value of Player1. what i wanted is if the player tries to drag this part and the ownername value is equal to player then the part locked is false. I tried everything playing with properties but i can't get it..
