Your campaign is correct. Do you have it located in a "scripts" folder within the "fritzbot" folder? If so, you need to have sv_pure set to 0 in either the console (/sv_pure 0) or in your autoexec.cfg (seta sv_pure "0"), or in your ET Start menu (pure server = NO).
Otherwise, you need to place it in a *.pk3 file in your fritzbot folder, which is simply a zip file with the extension renamed. Here, I've done it for you and tested it and it works. I have to send it as a *.zip file because the forum will not accept *.pk3 attachments. Simply change the extension to "pk3".
