[ic] ic4.8.2 Sales tax wierdness

[DB]

I have ic 4.8.2 installed on RedHat 7.1 using the foundation demo. I 
have modified a few of the templates and html pages but nothing major. 
Using the Wizard, I told it to charge 7% sales tax in Ohio.

Now if I place a test order for a taxable product and choose Ohio for 
the state, I get a popup saying that $0.00 tax will be charged and 
indeed no tax is added. Maybe I broke something when I modified a 
template or page, but can someone provide a troubleshooting tip or two? 
Other than this problem, everything works great!
