Thanks for that. Here's where I'm confused:
1. In your suggested 'else' you say to get the values from the form.
Where do I create the form? Do I do it there (as well as in the GET
branch)? I'd like to create the form only one time.
2. You say I do a form.process in the GET branch? I

I have a 'regular' form (i.e., FORM, not SQLFORM). I want to prepopulate
some of the fields, but I don't know the values to use for them when I
first create the form. What's the best practice for populating field
'subject'? Is it using the 'element' function? For example:
form = FORM(

Thanks again.

I've seen this before but I cannot remember what's causing it.
I have @auth.requires_login() decorating several of my controller
functions. I log in first, 'go' to one of those controller functions/pages
in my browser, and I get challenged to log in (even though I'm already
logged in). I log in
de the web2py environment), then go to the grid, I see that the box is
checked. If I uncheck it, that 'takes'.

I have a form with a multi-select. If I choose one value and submit, the
value is set in request.vars.xxx as a single integer (e.g., 2). If I choose
more than one value and submit I get a list of string values (e.g., ['1',
'5']). If I select no values I get None.

So, if I

table name when 'addressing' the row, else I do use the table name. That
seems 'unorthogonal'. Am I misunderstanding?

Thanks; I think I have it. The SQL is:

FROM Meet INNER JOIN
Participant_team ON Meet.id = Participant_team.Meet INNER JOIN
Team ON Participant_team.Team = Team.id;
My web2py below implements that.
