[Zope] Pardon my ignorance, but...

Hello All, I am quite new to zope, but it's great fun! However, I am having trouble figuring out how to do the following: I would like to have a user search my (MySQL) database for a particular record, then return the record values in an editable form. After the user has appropriately edited the record values, pressing submit causes the database record to be updated. The SQL is not the problem, but chaining the forms together so the second receives the values from the first as its defaults is where I am stuck. Can anyone point me in the right direction? TIA.
