Here's a simple code that will enable your visitors to use the Love Calculator straight from your website. All you need to do is to paste it wherever in the HTML code of your site. It's plain HTML, displayed properly in all browsers. Here it is:
Check name compatibility at <a href="http://www.love-calculator.org">Love Calculator</a>!<br> <form action="http://www.love-calculator.org/form.htm" method="post">
<input name="one" type="text" size="15" maxlength="50"> Your name<br>
<input name="two" type="text" size="15" maxlength="50"> Her/His name<br>
<input type="submit" value="calculate!">
</form>
It will display something like this (without the blue box around it):
