yeah...wrong forum but the answer is that you'd just times them like this...

function compute()
{
var iLenFeet = carpet_form.length_feet.value();
var iLenInch = carpet_form.length_inch.value();
var iWidFeet = carpet_form.width_feet.value();
var iWidInch = carpet_form.width_inch.value();

iLenInch = (iLenFeet*12) + iLenInch
iWidInch = (iWidFeet*12) + iWidInch

iSquare = (iLenInch/36) * (iWidInch/36)
}


Making separate fields for Inches and Feet is the easiest way to do it because then you dont have to worry about getting two values from one field.

Or if you want to go a PHP route:

<form method="post">
Length feet: <input type="text" name="f" /><br />
Length inches: <input type="text" name="i" /><br />
Width feet: <input type="text" name="f2" /><br />
Width inches: <input type="text" name="i2" /><br />
<input type="submit" name="submit" value="Submit me!" />


<?php

$f=$_POST['f'];
$i=$_POST['i'];
$f2=$_POST['f2'];
$i2=$_POST['i2'];


$d = 1/12;



$q = $i*$d;

$e = $q+$f;

$w = $e/3;

$z = $i2*$d;

$x = $z+$f2;

$c = $x/3;

$v = $c*$w;

echo ($v)

?>

Math works, I tested it. The form is really ugly, but that can be changed. The hard part's done.
