hidden form - getElementById

[lilman]

I am trying to change a hidden form's value with this code:

 

function togglePhoto(formname)

{

  document.getElementById('hiddenformname').value = 'My Value';

}

 

and trigger by:

 

<a onclick="togglePhoto('name');" href="javascript:void('')">

 

If anyone could help me out.  I just want to be able to change it's value upon clicking a link.

I'm confused... "form's value"? You mean an element in the form? I don't see any code to that effect.
