ok i can't just paste the html code from the html file to the textbox in the block admin page because it is a file that is generated every 5 minutes...
this is what i have so far...
i made a block-Myblock.php file in the /blocks folder...and wrote:
include("myfile.html");

for some reason the content of myfile.html is displayed outside of the block in the main page... anymore help please?
