bash script needs tidy up and revamping

I have a script that was made a year ago and revamped at Easter , but the freelancer on here never finished it and has left it with some bugs and now is awol and not replying to emails. The script is 4parts a part called codegen, that is where i can add my url to files to save and also edit ports or urls for a code to be made when a user presses a button a [login to view URL] that is used for custom code that is used with the amember script (google) a [login to view URL] that when a user buys a memberhip is copied to this file so a user cant try and cheat the systerm by buying/making a line straight after each other. a cron file that runs each other, i think this needs changing to each min The problems im having. When a user buys a membership and that ends via a enddate, the user then goes to buy a new longer code and when he/she comes to press the button a error comes up saying al ready made one. it seems that the new transaction is in the transaction file, but the bash code is not seeing it? too long? hour cron? anyways i need to work that a user can buy and make lines correctly and of course cant cheat the systerm 80% of the work is done, so dont quote me silly prices. any one not quoting, "bash auto code" we be removed as im fed up of all the india uses who dont read
