calculate 2nd serial number based on dates entered

[marysilvaramos]

Hi guys!

I am scratching my head finding the way to create a calculation which create a 2nd serial number of transplants based on the transplant date. Here are the details:

A patient can be transplanted several times, my users want to know which number of transplant it is. Data sample here:

Pat Name Transplant Date Transplant No.

JD 08/01/2000 1

JD 09/13/2000 2

JD 01/01/2001 3

I want to create a calculation field to calculate the "transplant no" . . In addition, I must to say that some records might be marked as "deleted" (The table as a field called "deleted" which marks the record when the user deletes the record). The deleted records should be omitted from the calculation.

Thanks in advance,

Mary

Assuming your "data_sample" is a field, use Right(data_sample ; 1). This could be put into an If function: If ( deleted <> "deleted" ; Right ( data_sample ; 1 ); "" )

I'm assuming (hopefully!) you don't have patients with more than 9 transplants! Also, I'm assuming that patient initials are always 2 characters. In retrospect, I think it would be better to have a join file: patient_transplant, with one record per transplant. Really, you should use patientID as a key field. Then you could concatenate the patientID and an underscore and the transplant number as your serial number.
