Previous Record, Different Field?

[pensive]

Remind me to wash all of your cars or something...for all the help you guys have given me.

I have a field -- Visit Date

I have a field -- Last Visit Date

I would like Last Visit Date to automatically contain the field from 'Visit Date' in the last related record.

more specifically, a patient has a visit. and we want to know when their previous visit was in a field.

i would love to have this as just a calculation field rather than a script...

is it possible?

Thanks so much in advance.

Create selfrelation such that Visit_Date<=Visit_Date and Patient=Patient

Sort your relation(let his name is Patient_Last_Visits) by Visited_Date-descending then your Last_Vist=Clients_Visit::Visit_Date.

If you can not do it. I will help you tomorrow. Be well.

To clarify, the relationship should be

Visits 2::Patient = Visits::Patient AND

Visits 2::Visit_Date < Visits::Visit_Date

You do not want to use <= or the current record's date will be included. You will probably be defining it in the opposite direction, and so will be using > instead of <.

Also, if you sort the relationship as aaa suggests, then you do not need a Last Visit Date field; you can simply put the related Visit_Date field directly on the layout.
