Have you tried cancelling the first registration?  I imagine the count against the incorrect option would then be correct.

I am not sure that you will find an easy way to do what you want.   

When faced with a similar situation we always cancel the entire registration and create a new registration with the correct choices, this keeps all the counts correct.

For the money side of things we have a price field that only admin can see called Previous payment.  In that you would have a negative amount that corresponds to the original event payment. (Yes, there could be many options needed, but I only add them as I need them)

You can then tick that option on the new event registration and end up with zero payment required.  This keeps the money side of things OK also.

It would help if you filled in the details in your profile to indicate which version of civicrm you are using.  If you are using many versions please include that info each time you start a new topic.

More rather less information will help others to provide relevant suggestions.

How is your event set up, have you used a price set?  (I use price sets for everything as I find them the most versatile way to operate.)

I can enter negative values for a price field option in both 4.2 and 4.4 with no problems.


 

Sorry about the version number, I am so used to seeing it in the profile on the left under the avatar that I missed it way up at the top of the first post.

You will need to make the option field either to radio button or check box.  Radio button will be quicker to set up - just create the option you need (and another with some random value if it makes you create two options (I haven't used 4.1 for a long time.))

A more versatile approach if you think others might make a similar mistake but will have chosen a different combination of paid events would be use check boxes.  You would set up one field option for each paid event with the "fee" being the negative of that event fee.   Then you just select the combination that comes to the amount you need when ever you need to re-register someone who has already paid.

First some good news, back office modification to event registrations is one of the new features planned for 4.5 (not sure if it will play nicely with CiviDiscount though).

Second, to you problem.

Perhaps I did not explain very clearly.  You don't enter a negative quantity into an existing price field, you create new price fields that are admin only that have negative amounts specified. ( See attachment)

If your event has a complicated pricing structure this can be a pain to set up and you may have to inventive to cope with the fact that you are using CiviDiscount, but it does keep the financial side of things accurate.
