Hi again many thanks for the reply.
First, unknown to a colleague and I, we have both been working on a separate part of a clinical trial Db. I did a relational style with subforms and she did a flat document style which just required filling in boxes or dropdown selections.
I have managed to bring together both Db's to make one.
The main problem I am having is that the clever clinicians now want the Db to record for each individual patient:
- Baseline visit
- Follow up at 6 months
- Follow up at 18 months
- 3 years
- 5 years
- 10 years
Each patient will be given a unique identifier as the primary key and another laboratory identifier.
What I am not able to do is, after filling in say patient 1's baseline details, on thier follow up at 6 months how do I get the new details into thier orginal table? All I can seem to do is have to create a new identity for the same patient. I am a NOOB to all this and only learnt on the fly, tight fisted clinicians not wanting to spend big £££'s on a professional Db. There are expected to be over 1,000 volunteers over the ten year period so with potentialy six visits each they will be storing a lot of data about each individual.
Hope this helps,
Regards
Doc
