Send data from flash -> php

first of all Hiiiiiiiiiiiiii people!

strange, very strange.
I can send variables from php to flash, but when I try to send variables from flash to php it doesnt work.

I have a dynamic text with Var="_level0.poemId" and I want to display it in the php file.

the text I use in flash is:
getURL (“php/read_poem.php”, “_blank”, “POST”);

and in read_poem.php I use $_POST[’_level0.poemId’] to get the value of variable but it doesnt display anything.

any suggestions about what I can do?
