Use custom user field in tax calculation... Need help.

[Lo_stalker]

Hi there,

I need to add to the tax calculation options a custom user field, so that different tax calculation is applied to the user if he selects different options in the registration process.

I've added the specific calc db table, modified the calc view and tried some custom additions to shopfunctions based on the existing calculations functions, but I can't retrieve and display the custom field values correctly.

Is there anyone that can help me with this?

I'm on vm 3.0.9 and j! 3.4.4

Thanks a lot!!
