I have a table three tables:

1- master document data
2- Review data (multiple reviews per master data)
3- Observations per review (multiple observations per review)

What I'm trying to do, is to include a form to enter the master data, that
links to a second form (linked through a button) that has the review form,
and the review form has a third form embedded as a subform. The review and
observation form works fine, but when the master data calls the review form,
it is not asigning the data to the master document. I know the relations are
set accordingly, but I think I missed a piece of code on the master data
button that calls the review form.

I am trying to get maybe a good book or a tutorial to link forms, because I
am using the form wizzard as a source, but I think I'm missing a part of the
code.

Thanks
