HTML: 

6. Style the text data as indicated in the selected radio button.

```
<label>xx-small</label><input type="radio" id="xx-small" name="rb" value="xx-small"  /><br/>
<label>medium</label><input type="radio" id="medium" name="rb" value="medium" /><br/>
<label>xx-large</label><input type="radio" id="xx-large" name="rb" value="xx-large" /><br/>   
<input type="text" id="styleText" value = "Random Text " /> 

```

My question is.. I can't seems to get the radiobutton to work properly by changing the fontsize in textbox. So therefore, how would I be able to fix this problem?

I'm sure I did something wrong but I can't quite seems to see the error that I have made.
