[Qgis-user] features that represent TWO attributes

[DelazJ]

You're welcome, dude...

The best thing is to reply to the list so that everybody is aware of
how/whether your issue has been solved or the workaround found or to have
other inputs that community can benefit from.

Sorry for the multiple times my reply was sent. This is due to a wrong
config on my cell phone that returns a fail on sending although the message
was really sent. Thus it retries to send again, and again (and it goes
every time until I stop it manually, what I did with a little delay
yesterday.... really noisy).
My apologies again
