[aur-general] Package Uploading Problem

Hello again XD I'm trying to upload the language pack for iceweasel, but when I try (https://aur.archlinux.org/pkgsubmit.php) I get an error which tells me It is only allowed to use small letters :S the pkbuild is the following: http://pastebin.com/bT4fdtPE It's taken from the parabolalinux official PKGBUILD ( https://projects.parabolagnulinux.org/abslibre.git/tree/libre/iceweasel-i18n ) Could you tell me why do I get this error?
