Hi,
Thanks for providing the extra information.
A quick answer is yes, you will need to do the prefs.get and assign it.
Currently you are stashing it in the user prefs, but you are not assigning
that value anywhere when you are showing the alert box.
The UserPref configuration appears correct. I am still not convinced that
your callback is doing the correct thing.
You would have do something along the lines of:
nument=data.num_entries
alert("nument is " + nument + ".");
prefs.set("num_entries",nument);
num_entries = prefs.getInt("num_entries");
alert("num_entries is " + num_entries + ".");
It is only doing the get, to get it out of the user preferences as you
already have the variable from the json object in the current scope.
