I think this has a pretty easy solution but I am pretty new to this stuf so I don't know how to solve it. I've created a php script and uploaded it to my page ( http://neriviktsnabbt.se/bmr.php ) and now i want to show it on this page: http://neriviktsnabbt.se/bmr-kalkylator/
What shall i write on the page to make it work?
