With my limited (very limited) knowledge of php I would appreciate some pointers...
Trying to multiply my cck "field_length" by "field_participants" to get the computed field "field_userdays". "length" is an integer (days) and participants is an integer too.

My computed field's pertinent settings are
Computed code:
$node_field[0]['value'] = "";
$node->field_length[0]['value'] *
$node->field_participants[0]['value'];

Set to "display this field"
Display format = $display = "$node_field_item['value'];"
Data type = "int"

I'm sure I have some basic code screwed up but the result is my computed field isn't showing. Thanks very much for any tips.

You have errors in your PHP code. It should be this:

Computed code:

$node_field[0]['value'] = 
$node->field_length[0]['value'] *
$node->field_participants[0]['value'];

(Note the first line - as it is, you're setting it to a blank string, and not assigning the computed values to any variable)

Display format:
$display = $node_field_item['value'];
(Note lack of quotes)

Try making these changes and see how it works.
