two actions, one text field, two dropdowns, multiple inputs

[kingQball]

So I'm trying to create a search box that has two choices based on a drop down box. Each selection does a different form action. On top of that, based on the selection made, it has different input values.
something like this:

<form name="search" action="ACTION1 or ACTION2">
<select name="group">
<option value="1234">Selection 1</option>
<option value="6789">Selection 2</option>
<input type="image" src="search.gif" alt="search button" />

if Selection 1 is selected it gets action - "ACTION1.php" and
<input type="hidden" name="direct" value="true">
<input type="text" name="bquery" size="24"  value="">
<input type="hidden" name="AuthType" value="ip,cpid">
if Selection 2 is selected it gets action - "ACTION2.php and
<input type="hidden" name="outside" value="true">
<input type="hidden" name="AuthType" value="wow, pow">
<input name="term" type="text" size="24">

I'm a real NOOB when it comes to javascript - so any help would be greatly appreciated

There are several ways to do this, but the easiest would be this:

<form name="search">
<select name="group" onchange="updateForm()">
<option value="1234">Selection 1</option>
<option value="6789">Selection 2</option>
</select>
<div id="content"></div>
<input type="image" src="search.gif" alt="search button" onclick="document.forms[0].submit();">
</form>
<script type="text/javascript">
function updateForm()
{
if(document.forms[0].group.value=="1234")
{
document.getElementById("content").innerHTML="<input type='text' name='bquery' size='24'  value=''>";
document.forms[0].action.value="ACTION1";
}
else
{
document.getElementById("content").innerHTML="<input type='text' name='term' size='24'  value=''>";
document.forms[0].action.value="ACTION2";
}
}
</script>
