I have 3 radio button options to chose from, but I only want one certain one to calculate a sales tax. How can I assign a calculation to one radio button?

Can you describe the full situation, please? Do you mean that you have something like a sub-total and a tax field, and the tax field should only be populated if that specific button is selected? Should it be zero otherwise?

That is exactly correct.

OK. Let's say the name of the radio-button group is "Radio1", the export value of that field is "3", the name of the sub-total is "SubTotal" and the tax rate is 16%. You can use this code as the custom calculation script of the Tax field:

event.value = (this.getField("Radio1").valueAsString=="3") ? Number(this.getField("SubTotal").valueAsString) * 0.16 : 0;

Where do I find the "Export Value Field".... I don't see it under properties?

Sorry, it got renamed to "Radio Button Choice". It's under Properties - Options.
