please can somebody help me?
I save data from Flex over PHP into a MYSQL database. (id, member_id, name, amount, date)
Save and read the data works great. Now i have to modify the application with a new function where i can subtract any amounts from the global amount. And the new amount (old amount - amounts = new amount) has to be show in a Textfield.
I have 2 new textfields (date, minus_amount) where i can write and save a new minus from the global amount.
And here i reach the end of knowing ... How can i realise this? Do i need a second table in the MYSQL db?
Thank´s in advance!
