Double click the following script when you share the project:

set [votable v] to [true]

Now add this script:

when this sprite clicked
if <(votable) = [true]> then
    change [Yes v] by (1)
    set [votable v] to [false]
end

Yes must be a cloud variable, but votable cannot be a cloud variable.

People can still vote twice if they refresh the page, however.
