User blog:Saboteur99/Help with templates

Hi everyone,

Sorry if this post doesn't belong here, but I don't know where else to put it. I am creating a wikia for one of my favorite tv shows, and I don't know how to make custom infobox templates for characters? Can anyone here help me? I've tried editing default infboxes, but can't seem to get it to work, and copy and paste from other wikis isn't working either. I appreciate any help.
