    Applying ID to Function

    Hi All,

    Apologies, but I am a bit stuck with getting a form button and action to work separately on each line of my PHP loop.

    Currently the first button works, but if you decide to click a button on another line the first field is populated and not on the line of the button pressed.

    As I understand it I would probably have to apply another numbered ID to the ID of the element i have already applied. But am a bit stuck on how to. (been trying for day and a half!)

    You can see the page in question here: http://www.jadeboylan.com/game/post.php

    The code here: http://pastebin.com/gUMSqJYy

    Any help would be greatly appreciated!

            echo 
    "You have $funds to spend!";
