We have a slightly customize osCommerce shopping cart website and our [url removed, login to view] gateway is processing the wrong amount of funds when taxes are applied. I need someone to correct the issue so the amount charged to the Credit Card is accurate.
Example of problem that needs to be corrected:
For orders that we tax on (GA, FL, TX) the amount that [url removed, login to view] receives/processes is slightly off (less) than what it should be.
For example, an item that cost $307.88 is taxed at 8.25% for a total of $333.28. That correct dollar amount is stored in the OSCommerce order but the total that [url removed, login to view] processes is $332.22. In this case it's off by about [url removed, login to view]% for some reason. However, it's not always off by that exact percentage...but it's close. This only happens for taxed items so I assume it's related.
Please bid on the assumption that you will only receive the [url removed, login to view] processing code/page (and any other files you need) and will not have access the LIVE system. You will send me the modified files with instructions to update. I will test the correction on our development server and let you know the results.
