[development] Problem with hook_form_alter: Cannot unset string offsets

[Steve Ringwood]

Whats the value of $var?

Because it's a CCK field you may need to use
$form[$var]['#type'] =  'hidden';
$form[$var]['#value'] = $nid;
to avoid clearing elements CCK expects to find.

(Side note: I would use 'value' instead of 'hidden')
