Hi guys and girls, I have question for you all. I have developed a flash application which is a test for students. For each test their is an accompanying excel spreadsheet that has information related to each question they have answered and whether they got it right or wrong. I am receiving whether the student got the question right or wrong in PHP from FLASH. That part is complete. The other part I have complete is PHP emailing the teacher with an attached excel spreadsheet renamed to the studentsname_results.xls....the last part I want to complete is that of the students results being inputted into the correct column in the spreadsheet and then being attached to the email. I am guessing I would be best to not attach a physical file that resides on the server but build the data up inside PHP to resemble the file format I am trying to generate and attach that to my email. Two questions. Can someone tell me the best format to be sending (i.e. the format that has the best support for PHP) and also is this method dependent on the web server being windows or linux based. I am no expert but from what I can gather I take it that COM object support is really just for windows based web servers. Thanks and all the best, Nathan
