Scott,
I am currently running SmithCart version 4.86 on DotNetNuke Community Edition 06.00.02, The client is requiring us to calculate tax for thepurchase based upon the county where the item is to be shipped to in the state of Ohio. Despite using your instructions the tax is constant at 7% no matter what county I select in the checkout process.
Under Tax Setup in the General Store Setup I have selected the radio button to Use Tax Tables. In the state listing I have selected Ohio and ticked the Use Step One Drop Down List in Tax Menu.
Moving down to Checkout Step One Settings: I ticked the Show Drop Down and In the Label Box put in "Ohio Counties" and then filled the drop down list values with the county names that matched the tax table information I uploaded in the population of the tax table from the cart tool box menu.
In addtion when runnung through the check out process the county selection is not required as is what is outline in your post. Please advise as this is a real show stopper for the client not to mention this seems to be an out of the box feature that should just work.
Thank you,
