I am trying to dynamically change the options available to a user. A user will choose either 1 or 2. Once they choose a value, I need to load the options associated with that value. Currently, i have the following:

```
var json = {'1':[{ 'value':'A', 'text':'Option - A'}, { 'value':'B', 'text':'Option - B'}], '2':[{ 'value':'A', 'text':'Choice - A'}, { 'value':'B', 'text':'Choice - B'}]};

var userWants = '1';
alert(json[userWants]);

```

Oddly, the alert window just displays `,`. I don't understand why. What am I doing wrong?
