Hi,
I have been looking for an answer the whole week to this problem:
I have a table Patients with a Combibox patientID and another Combibox
PatientName.
Another table Treatment with a listbox patientID, many-to-one related to the
first patientID (plus a lot of other fields...)
For a new patient I need to use a form NewPatient updating the table
Patients, no problems... Going from this form to my Treatment form I want
the new patient data to be included in the Treatment form, that is: I want
the Treatment form to show the new patient data ONLY if I use the
NewPatient form, OTHERWISE I want lists view of old patient names and
patient ID in the Treatment form.
AND how do I connect the PatientID field and the PatientName fields in my
Treatment form so when selecting EITHER PatientName OR PatientID the other
field automatiaclly updates w the corresponding name/ID from the Patients
table? It is SO D*d frustrating... I have been programming 20 years, but not
database stuff. I am in deep water, no swimming available. Please have mercy
with me...! Give me a hint!

By not putting the PatientName field in this table AT ALL!

In a relational database, you try to avoid redundancy. If you store a
patient's name, you store it ONLY ONCE - in the Patient bio table; if
you need to see the name in conjunction with treatment data, you store
the PatientID (only!) in the Treatment table, and use a Query or a
combo box displaying the name while storing the ID.
