For a christmas-action from my sportteam, I made a form to order some christmaspackages.
Now I would like to add the totals to the form, so you can see right away how much you will have to pay while filling out the form

Here is a link to the page so far :http://www.sportingneerpelt.be/kerst_test.html

I would like to add a totalbox per item and one total for the whole thing together.

Anyone an idea how to do that?
