Well, I'm making an application that has a competition of
football. It is the creation of a new league to let him
associate some equipment (eg 20), which is read from a table
teams prepared for this purpose.

Once you create the league table automatically created in the
"Match" (20 records) to keep the data of each team
in this league, such as goals, points etc ...

Turn into another table of "Encounters" is also automatically created
many records as events generated in the league (this is
calculated using a formula and leave the games of the season) these
records will be empty, only generate the record with
associated identifier (will be filled when you enter
outcome of the meeting).

Well this way either through triggers in the database (from
the results of matches and goals to the points table
classification) the application is maintained.

After explaining a little above the problem I'm going to
specific problem.

Take league form data and also lead the league
embedded (that is the way it happened to me, among others
discarded) a dynamic form in which according to the number of
equipment that we want we will be adding or deleting records to the
League table, as we mentioned at the beginning.

This I have tried embebiddos forms and have not succeeded,
I also tried double teams and select lists
you want but do not, another option that probe is of a select
multiple.

Note that the classification table has an id, and a team
(Among other fields) where "team" is a foreign key to table
equipment, discussed above. (This seems to me a bit complicated
but the operation).

If someone would kindly help me I would send more code
specifically to see how the situation in time for you
I hope to see as they serve.

Regards and sorry for the chapisima that you just get! jajajaj
thanks in advance.
