More information would be useful. What module are you using for the ftp interface? Also the line $ftp->get($file) and $ftp->delete($file); struck me as odd. Again as I do not know what module you are using I can't say for sure but it seems like you wouldnt want to get and delete the file before you do anything.

Also for future reference, please spend five seconds doing a simple proofreading of your post. When 50% of your title is misspelled and 25% is all capitalized many monks will answer other people's questions first.
