Hi Kelli and warmly welcome. I'm afraid I won't be able to answer your questions but just want you to note that many here get their google group postings via email. This means that edits (addendums) to a post are not seen. So I'd recommend that you simply add a new post below the first instead.
As for the red errors, it would be useful if you can describe the exact steps that produce it. That way it can be investigated. <:-) > > -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
