I had someone create an application on a ecommerce site that sells a limited amount of items by paypal. The total quantity of items is shown on the site and when someone purchases one, the total amount of items remaining changes and the new total is shown on the site. It works fairly well except sometimes when one is purchased it subtracts a quantity of two or not at all. Gift certificates are also sold on the site and work in the same way except they generate a code that is used when they redeem them for an item. So that redemption needs to work similar as a purchase by changing the quantity remaining.
There is also an admin page where the total quantity on hand can be input. That has a small issue where it can't be adjusted if they decide to add more items. Example is if they are selling 10, and sold 3, and then when adding 2 more the total on the front end still reads 7 remaining.
This system actually works pretty well and the bug is probably something very minor that just needs to be uncovered.
You must know php like a champ. This is an emergency fix and I need someone to take it from start to completion NOW. If you are ready to stop for the day soon or can't finish it today, please do not bid. This is a LIVE ecommerce site and can't wait.
You are bidding knowing that any bugs that emerge after you fix it will also be part of this project and your responsibility. In other words, you will own this once you work on it. The bugs I mentioned above are the only issues I'm aware of.
I will escrow the funds, but will release them after 7 days when I know for sure it's fixed.
budget is $60. As I said, it works well except for something that probably is easy to find if you know php programming well.
