savevalue
The savevalue command allows you to save a variable for a user that can then be loaded again in later sessions.
You can use it to save the group that users have been randomised to:
savevalue(username, "group", "web")
You can use it to save the time users have seen a particular page:
savevalue(username, "s1time", currenttime())
You can use it to save the response that they have given to a single or multiple-choice interaction:
savevalue(username, "fatigue", page1.interaction1)
N.B. You must use a Next type button on the page that you are saving information from when you use savevalue. If you use a Jump button, the logic referring to savevalue will not be read and so the variable will not save.
