Include PHP script into a page, HELP!

First of all sorry about my poor english, I?′ll try to be as clear as possible…
Well, I?′ve installed an ask & answer php script to my site (I?′ve installed it in a folder called “askme” inside my wordpress folder), it works just fine (https://www.push-play.com/wp/askme/askme.php), now I want it to show in one of my wordpress pages, but when I try to include the php in the page template this is what I get
(https://www.push-play.com/wp/?page_id=26)
I?′ve tried the RUNphp plugin and it?′s not working, I?′ve also read every single topic about php in pages here but can?′t solve my problem. Would somebody help me please!
