Thank you.

I added a section to unset all post variables with no data:

PHP Code:


if ($_POST['VD'] === '')
    {unset($VD);
    }
    else
    {$_POST['VD'] = $VD;
    }
    
    
    if ($_POST['HD'] === '')
    {unset($HD);
    }
    else
    {$_POST['HD'] = $HD;
    }
    
    
    if ($_POST['TD'] === '')
    {unset($TD);
    }
    else
    {$_POST['TD'] = $TD;
    } 


It's calculating everything correctly now, and it's not giving errors, but it's spitting the answer out on a blank page.

How can I take my answer ($TD) and set it equall to .htmlspecialchars($_POST['TD']). so that it displays the answer in the unfilled form field?

can I just use:

PHP Code:


.htmlspecialchars($_POST['TD']). = $TD 


Thanks,

Nick
