CiviCRM Community Forums (archive)

First, thanks for all the work put in on creating CiviCRM! 

Second, I know I know, this has been adressed before, but the post I found that was closest to my problem (http://forum.civicrm.org/index.php/topic,4286.msg18683.html#msg18683) provides a solution that for me gives an error message (of course, I may be missing something, but for the life of me, I just cannot see what). 

I want to create a contribution page that does two things:

1) Creates a new member record
2) Gives the option to add an extra contribution (preferably a pre-defined sum, as it is supposed to be rental fee for storing a kayak in a boathouse)

These are for accounting purposes to be treated separately (separate accounting accounts (does that make sense? I'm Norwegian, see..)), but in the same contribution sum (i.e. one transaction).

This is what I've done:
I've created a price set with membership fee and boathouse rent as two fields.
I've created a contribution page and checked the field "CONTRIBUTION AMOUNTS SECTION ENABLED". But when I try to check the box "Separate Membership Payment", I get the following error:

Please correct the following errors in the form fields below:
You cannot enable both Membership Signup and a Contribution Price Set on the same online contribution page.

If I try to do this the other way around, first enabling the Separate Membership Payment, I get this error message:

Please correct the following errors in the form fields below:
Please enable the contribution amount section to use this option.

Of course, if I try to do this, checking the CONTRIBUTION AMOUNTS SECTION ENABLED box, I get back to the first error again...

What am I missing? I thought from the comment below the "Separate Membership Payment" box, that this was for enabling just this feature? Or  have I misunderstood something (again)?

I'd really appreciate help on this! Thanks a million in advance!
(And if there's another way of doing this and making it work, I'm open for all suggestions!)

edit: forgot to mention I'm using Drupal 7.8 and CiviCRM 4.0.6.

And I should have asked if you have replicated this on Demo?

And are all Norwegians making fun of themselves 

Um - did you tick a Membership Type on the Memberships tab of the Contribution Page - and by select i mean 'tick' it on the left, not the 'default' radio buttons on the right (which has tripped me up several times)
Its great having toddlers to blame - like being able to say 'the dog ate my homework'
