Skip records with the same value
I am looking for a way to filter records with “double value”.
I have a table with information about students of a ground school. In this information there is a mail address involved. This can be their own mail address or the mail address of the parents. (depending on age).
The school automatically generates mail with FMP. Works all fine. But… there are parents with 2, 3 or even 4 children.
I am looking for a way to skip the records with the same mail address, but I can’t find a proper way.
Is there someone with a good idea to skip records with the same value?
Thanks in advance.
