lmao I got this before simple its taking away and adding. command: :shell (username) +50 for Positive Credits, Pixels, Or Shells, For Negative :shell (username) -50

That didnt even help a bit , I didnt ask for info , I asked if anybody could fix this to prevent it from decreasing more than 0

Run a query to grab how many points the user who is sending them has:

$query = "SELECT `vip_points` FROM users WHERE username = '$from';
$points = mysql_query($query);

Then an if check to see if the amount is more than what the user has:

if $points > $amount {
echo 'You do not have that many points to transfer.';
} else { run other queries to transfer points.

I was referring to the people whose support tickets I've been handling.

For example, Kevin of ameca.org wants to know why he has to have a password for his billing account and a different password for his cPanel...
