PHP Post data

[azteck2]

I tried making a template out of the pushout.php page and using the get_url function but it did not work, I only got the part of the echo statement that did not contain variables, as if the post data never made it. I tested this by just echo'ing the variables I assigned the post data to and they were both empty.
I also tried adding custom pages and using the component feature to add the php but that gave me the same results.
Can you tell me how to make a form and pass post data to another page?
