Can I use radio button to insert text into text field?

[wvmlt]

I have a text field on my site

<input type=text name=useravatar value=\"$useravatar\">


where users can insert the url of an avatar. I would like to present the user a group of avatars to choose from and when one is selected, have the url entered in the text field. Can I do this or do I need to just enter the url next to the avatar and tell users to paste the url of the avatar they want to use?

You would use JavaScript and it go something like the following:

<script language=javascript>

function changeField(rName) {
eval("document.formName.useravatar.value = document.formName." + rName + ".value");
}

</script>


For the radio button:

<input type=radio name=serveravatar1 value="addressOfServerAvatar" onClick="changeField('serveravatar1');">

Course you could do the changes inside each radio button, and if I am not mistaken, in JavaScript, if your change "changeField('serveravatar1');" to "changeField('this.Field');" will reference the current field calling the function. But don't quote me on that cause my memory is fuzzy in that area right now...
