Sending to groups in recordset?

Hi
Just bought UE4! And I have it working from local with MAMP. So far so good :)

Maybe the title is not correct. But what I want to do is this:

I have a recordset with all the clients to recive an email. In the recorset they are grouped in different districts by a "district" column.

Now in my email page I want to choose a district and mail to only those in that district.

So if I for instance have a select list and choose district A. Only the persons with A in district column will have an email. Selecting B to persons with B in district column and so on ...

I need it so that the client sending the mail easy can make a choise to filter all the records into groups based on a value in the column. And send to that group only. (or to all at once).

Well, I hope you understand what I want to do. And that this can be done :)

Regards
Olle

Hi
Nevermind. I figured it out.
I put up a "jump select list" on page to select district. And then filter the recordset with a URL parameter on the UE page.

So coming from the select page with district values in the select list. I get "email.php?distrikt=CBU-1"

And because the recordset in the email.php page is filtered with the URL value. It only sends email to "CBU-1" district in this case.
