Thanks for the tip.
I have now added the following 2 functions to my code:
function setStates(obj) {
this.states = obj;
}
function getStates() {
return this.states;
}
function StateSuggestions() {
$j.getJSON("client/ajax/getMedList.php", function(data){
setStates(data);
});
}
And things are now working beautifully.
