You would have to supply the callback function for the notification. This post has an example of how to apply it:
You would then do what you did for the chat script and have an if statement that compares the result:
function bindable.OnInvoke(response) -- code taken from the above post
if response == "Yes" then
-- Fire a remote to the server to give the coil
else
-- Player selected no, therefore do nothing
end
print(response .. " chosen")
end
