i bought a prozilla automall website and i have found a glitch in it.

currently, if a member purchases a package from me that contains 5 profile listings that last for 1 month, at the end of the month they will get an email that says that their listings are expiring and need to be renewed.

well, if a person logs onto my site, and purchases 1 new listing, all of those other 5 now have that new listings expiration date. (all listings contain the same expiration date, whichever one was bought last is the date they all expire.)

does anyone know if it is easy to fix this type of code? I want it so that each listing that is bought, carries it's own expiration date.

also, how much would be a fair price to pay someone to do this for me?

Thanks.
