Checkout problems

OK, well calling tech support has done us no good, so hopefully someone here will help me with these issues:

1) We can't get rid of the flat shipping rate option in the checkout process. Anytime we turn it off in salescart.asa, everything breaks. Also tried replacing the cgi-bin/shipping folder with new clean copy, and everything broke.

2) We're not getting any rates back from USPS, even though it's turned on and user/pass are also included in shippingini.xml

3) We've been getting "security error" emails about duplicate product ID's etc. I turned security error emails off in checkpost.asp since I have no idea why this problem occurs in every cart (something in shop1.asp?)...

Thanks

OK, the flat rate shipping option is at the very top of the options... I've changed the name to "Pre Arranged Pickup" so that people won't all automatically go for the free "Flat Shipping." The only other options on the page are UPS.

USPS has checked the account setup several times and yes, it's on a production server. Their server is not even receiving any rate requests from the cart.

I've added the path.asp include to the product detail page (the only page that uses product links/add to cart) and I have changed the checkpost file back to allow error emails. This might have been a fluke while we were swapping files around and troubleshooting some merchant account problems... I hope.

We still need answers for these problems! I finally gave up on the security email issue and turned those off. The SalesCart Knowledge Base fix didn't help at all, go figure.

We STILL aren't getting USPS rates. The USPS server isn't even getting request for rates.

Anybody??
