you have to check the UPS settings   http://docs.abantecart.com/pages/ship_and_pay/shippings/ups.html

I did check all settings. Only thing missing was the box size, which I added. Still having trouble with UPS. It's giving me an error message when I use the shipping estimator: 110108: Missing/Illegal Shipper/CountryCode

Thank you for the examples. I checked my tax settings and they pretty much are the same as in your examples. There is one difference, though. When I set the tax rate for both states, I entered a percentage (e.g. 7.5 for California) and left the field right below blank. After I saved the settings, the blank field was populated with 0.0000 and this is what I'm showing now:
"Apply this tax only if, taxed amount (product, shipping, subtotal, etc.) is ... 0.00000". In the shipping/tax estimator, it's not showing any tax estimate for either state. Then I changed the above expression to "Apply this tax only if, taxed amount (product, shipping, subtotal, etc.) is > (greater than) 1.00". Tried tax estimator again, still having the same problem. It's not showing the sales tax for either state.

I'm not getting a response from Algozone's Tech Support so I'm posting in this forum, hoping someone can help me. I've been trying to get assistance for two days now and no response!! They're useless. Even when I said I was interested in other extensions, nobody in the company bothered to call me back! Anyway, I bought their Advanced Search extension, but it's not doing what it's supposed to. Their ad says this extension allows advanced search using multiple filters, including the Tags filter. It turns out that I'm only getting one filter on the screen, the Price filter, and that's it. Nothing else is coming up. Not only that. When I run a search by Price, I get this error message: "Call to undefined function array_replace_recursive () in /home/.../public_html/store/core/lib/request.php on line 53." What the heck does that mean? Why am I not getting multiple filters on my screen? Is this a rotten apple? What do you do when a company sells something and doesn't stay behind their product?

I set up both UPS and USPS, but only USPS is being displayed at Checkout. For some reason, UPS is not. How can make sure both shipping methods are available to my customers?

llegrand, thank you for taking the time to give me a thorough answer. Very much appreciated. I'm looking forward to setting up a multi-store. Each day I get more excited about Abantecart and what it can do. :-)

I'm considering Abantecart in place of my paid shopping cart. I spoke with the shopping cart vendor only to find out they won't allow me to use it in a subdomain unless I buy a new license. In this case, I would need to buy 10 licenses at a cost close to $4,000. My question is for a DEVELOPER or someone who's VERY FAMILIAR with Abantecart and can give me a straight and reliable answer. My goal is to implement GTranslate on my website (not to be confused with Google Translate). I tested it on my website and found out it won't work when I get to the shopping cart. It gives me a license error code. Considering that Abantecart is open source, can I use it on my subdomains? If so, do I need to install it in each subdomain? Currently, GTranslate works on any of my non-secure subdomains. I understand I would also need a wildcard certificate to secure the subdomains. I don't feel like spending $450 on this certificate unless I know for sure that Abantecart will work for me. Thank you for your time and attention.

When I try to access the migration tool, I get this error message:

Fatal error: require_once() [function.require]: Failed opening required '/home/azhea3/public_html/store/admin/model/tool/migration/_vti_cnf' (include_path='.:/usr/local/php52/lib/php') in /home/azhea3/public_html/store/admin/model/tool/migration.php on line 735

I appreciate if someone could tell me how to fix the problem.
