Need help accessing the values of an array in a form ...

Hi, I have a form using the post method that outputs a dynamic number of fields each time with the same name but different values - this is required. For example ... filename[] filename[] filename[] filename[] On the next page I try to access the array using ... for($i=0; $i<count($filename); $i++) { $value = $filename[$i]; do something with $value ... } but $filename[0], $filename[1], $filename[2], etc each contain one letter from the word "Array" if there were say five items in the array!? What am I doing wrong and/or how do I get the actual values?
