hi -- I have an HTML javascript header that defines a function. The first snippet of code is:

<script LANGUAGE = "JavaScript" src="http://www.json.org/json.js"></script>

<script type="text/javascript">

function lookupObjTypeID(){

alert ('Running javascript');


// Continue only if there's a value in objecttype_name field

if ($v('P3_OBJECTTYPE_NAME')){

...

The alert works, so the JS is getting executed. But I get
$v is not defined in the FF error console. I use $v several
places in the function, and every one causes that error if I
modify the code to get to that statement.

I've also put this into an incredibly simple page header, and
get the same error.

What am I doing wrong?

Thanks,
Carol
