a couplf of fast tasks

Hey everyone I have a couple of tasks I need some help with to get completed. I wil try to give you details on all them best I can. First task : Form error with this I have a page in my admin panel that allows editing to be done now if they should edit but add something extra in they would enter the info and of course update it but when I pres the update button it says its missing but the info was entered. This page is a lil tricky but I am sure its a simple fix. Second Task : Cron job addition With this task I added a feature in that would return the invested amount BACK to the user when the plan expires. So what I need is to add this to the cron job file (I have some code) so when it sees that its the last payment it will give the interest plus the invested amount Back to the user. Third Task : Cashout Limit With this there is an option in admin panel called "Enable cashout limit" now if this is enabled the admin will enter a number and then choose day/week/month meaning they can only do it this many times per day/week/month. I have some code for this but I need the cashout page to check this for being enabled which I have and then check the table which I can provide to see how many times the user has done a cashout and check it against the number and if its day/week/month. example. 2 cashouts per week then if i have already done 2 then when i try the 3rd one in the same 7 days then i would get a error msg. PROFIT SHARING : The user buys shares at say $3 each well the full return is say 150% so then lets say they buy 3 shares for $9 that means at the very end they will get back $13.50 which is 150% so I need to have it stop the earnings onces they have hit and set the share purchase to non active(at least I think thats how I have it) For each of these tasks I can work with you and provide you access to what you need. This is a private script created by me I just need to add some other stuff to it and this is the last of it. Good luck and serious bidders only. Live chat is what I prefer so bid if only you are willing for live chat. Thanks
