Hi,
This is a repost of : https://forum.awareim.com/d/7931>
Basically if you want to have a string composed from multiple attributes you can use LIST_LINE function (find in user guide)
From this:

you can have this:
attribute = " Loading 1, Loading 2, Loading 3, Loading 4, Unloading 1, Unloading 2, Unloading 3"
cheers,
