Desperately seeking assistance

I'm working very hard to make Zoho Creator work for me. I must be very dumb, but things just aren't working out. I am a volunteer book review editor, and I need to maintain a database of which reviewers have which books. There are some date calculations, easily done in a spreadsheet (I've been maintaining the list in Google Docs), but a database would just work better for me -- reports, etc.

Is there someone out there who will volunteer to write the field specs for the calculated fields? I don't think they're that complicated, but I simply can't get it to work right. I think an experienced person can get this done in less than ten minutes.

Thanks so much for considering this. My e-mail address is jeff.needle@gmail.com, if you want to correspond privately.
