Hi mac,
my fmod page works well, but there is one thing that worries me, when I click the link of my fmod page on a menu, it gives me a warnig: Warning: fmod() expects parameter 1 to be double, string given in C:\Program Files\EasyPHP-5.3.3\www\fmod.php on line 41, but everything works well, here is my code

Language: PHP
EDITED: You cannot post ALL your code here!!!...

Just use a form that will allowed a user to enter the number (value for $x and $y), because what I see here is you assign the value $x to a string "undefined" why?
see below:

Language: PHP
$x = $_POST[';x';];
$y = $_POST[';y';];

This way you'll not going to get that warning anymore, remember that you'll get those values from the form.

fmod() expects you to pass it two floats as arguments. http://ca.php.net/manual/en/function.fmod.php

To the best of my knowledge when you capture data from a form you get a string type.

You can check your variables for their type using gettype()

You need to do type casting or juggling to solve your problem
