Simple Math between fields?

Hi,

I was wondering if it would be possible to add some simple math (addition) between fields.

As it is much easier to see it than explaining it, please goto:

cupertinomiddle.org/pta/signupdonations

After the donation radio buttons, I have a few checkboxes (non exclusive), that, if checked,
would increase the donation amount.

Would it be possible to implement it with your extension?
Thanks in advance.

Best regards,
Max

Hi

In the current version , It is not possible . I will add this nice feature to the next version of Joom Donation for sure (Infact, this feature was implemented in one of my extension called Payment Form (Fee field feature) .

If you need this feature shortly , maybe you can hire us to implement it for you .

Thanks ,

Interesting. I was not aware of Payment form extension. I think it might do exactly what I need.
My question for you is:

Would you be so kind to point out the main differences between Joomdonation and payment form ?
They seem very similar and it is very hard for me
to understand why choosing one over the other.
Thanks again and keep up the excellent work!
