Displaying a variable in a text box

[badge]

Hi all, need a hand,I've defined a variable "sonic" with radio buttons and can display it using

<input type="button" value=Display onClick="document.write(sonic)">

However, I'd really like to show it in a text box next to the button (currently get taken to a new page), and can't for the life of me work out how.Any help greatly appreciated, Badge.

<script type="text/javascript">var sonic = 'something';</script>...<input type="button" value=Display onClick="document.getElementById('txt1').value = sonic"/><input type="text" id="txt1" value=""/>
