Hello,

Im get the following error message:

Warning: Division by zero in /home/find-a-w/public_html/bmi.php on line 16

PHP Code:


<?

if (isset($X2))
{



echo (($Y2 * 703) / ($X2 * $X2));


}



?>

The value for Y2 is 200 and the value for X2 is 71.

Anyone have any ideas?

Thank You,
Brian

tested it and it works fine, you obviously have not set X2 or Y2 previously in the script! try this instead:

PHP Code:

if (isset($X2) && isset($Y2))

Hello FiRe,

You're right. What I ment to say is that I get that message when the fields are not set. I tried your way and I'm still getting the error.

You shouldn't be using isset alone. Instead, use other alternatives such as floatval:

PHP Code:

<?php
if(floatval($X2) != 0)
{
    echo (($Y2 * 703) / ($X2 * $X2)); 
}
