Populating an array to the next script!

Hello, Is there a way to populate an array from one script to the next one? I'm using a form, and a hidden field for such desire: <input name="hwt[]" type="hidden" value="<?php echo($hwGSM);?>"> but it returns this: <input name="hwt[]" type="hidden" value="Array"> then I pretend to read the array again at the target script by coding the following: $hw=$_POST['hwt']; $hwGSM=$hw[0]; for($i=0;$i<=$maxpoint;$i++){ echo($hwGSM[$i]); } It should be pretty easy but I have not done it ever! Regards, Miguel Guirao P.S. I can not get rid of of the below crap!! I know is annoying, but it's a policy!
