I have a PayPal button I need to say "Sold Out" after clicking on it. When the button is click on the shopping cart, I need to run PHP code that adds "M1" to a file "trackOrder.txt". Then it checks the file for the string "M1". I will have other buttons will record to this file as well.
I need help combining this together so it functions. I currently initiating onmouseover for testing purposes.
