= Adding a participant identifier from the panel system =
You can add the participant value that you received from the panel system. This way, if the participant returns to your page (or for instances presses F5) he will receive the same counter value and hence the same version of the experiment.

If you combine a ''participant'' value with a ''timeout'', the ''timeout'' will be reset to the new value, giving the participant more time to complete the experiment. Setting timeout on a finalized experiment will not result in an error, but will not reset the ''timeout'' value.
