Hi Carl,

sorry I could not followup earlier.  I also had to debug my code until
I found how it had to work, there are not so many form_alter examples
available. I try to help you, however I am not a real expert.  And I
hope that the thread is acceptable in drupal development.

I added material to the form as follows by adding one array element,
in your case it would be:

$form[$category]['edit-profile_matchmaking_2006'] = $alteration;

In setting up $alteration you can use '#weight' => <number> to
position your addition.  Note that profile does not set weights, you
may have to set weights alco for the other array elements to reach
what you want.  Not using weight means (I think) the PHP ordering
prevails, which (I think) means first assigned array members are

The code asks for what you observe...

$form[$category]['Medlemskonventet 2006'] = $alteration;

should also have worked.  The firs array_merge statement in your code
is ineffectual I think.

In order to decide where your addition is rendered you need to use
weights (see above).

It is indeed possible to alter profile forms with form_alter, the code
snippet I sent previously works for me (Drupal 4.7.x).
