Thanks.

Does this work:

PHP Code:
//we place all the values into an array so we can run a function on them

$values = @array($HD$VD$TD$Dv$Dh$PC$FC$V$A$W$FA$MFv$MFh$GT1$GT2);


//we check to see if the user has filled in at least two variables

function atLeastTwo($values)
{
    
$counter 0;
    foreach (
$values as $value)
    {
        if (
$value !== null)
        {
            
$counter++;
            if (
$counter == 2)
            {
                return 
false;
            }
        }
    }
    return 
true;
}



if (
atLeastTwo($values))
{
    die 
"You Must fill in at least two fields before calculating";
