This is a calculator to help cost Australia's capped mobile phone plans. It assumes that data is included in the cap; this is only true of some caps so be careful. I'll fix this later.

This used javascript embedded in Jooma, using Dojotools to provide the form styling and validation, first time I've done this. How I did it is here, Now, this page is a better example of using dojotools.

At the moment, that means that the form strictly requires two decimal places in dollar value fields. If the data charge is $2 a MB, enter 2.00.
