document.getElementById(hide).style.display="none";
}
</script>

<input type="radio" name="relationship" value="trained" onClick="show_hide('trained', 'tutor')" checked /> Trained  <input type="radio" name="relationship" value="tutor" onClick="show_hide('tutor', 'trained')" /> Tutor

<div id="trained" style="padding-top: 10px; display: block;">
I was trained by: <input type="text" class='input_text' id='username1' name="username1" size="30" value="{$user_name1}" tabindex="0" />
</div>


<div id="tutor" style="padding-top: 10px; display: none;">
I was the tutor of: <input type="text" class='input_text' id='username2' name="username2" size="30" value="{$user_name2}" tabindex="0" />
</div>

<div id="tutor" style="padding-top: 10px; display: none;">

</script>

Notice the two highlighted areas. The first is a comment but will be required for some browsers in some cases (like Firefox or Opera, if the page is in standards mode) if you want the code in the second area to execute when navigating to the page via the browser's back or forward buttons. If so and that's what you want, uncomment it (remove the red slashes).

The second highlighted area is what does the work by setting the [0] indexed (the first) radio to checked. Since only one radio in a group of two or more of the same name may be checked, the other will be unchecked if it was checked.
