Custom box: speed of the leader (1st) ONLY.

And this is the "stored values" tab:

Ye that looks fine.
Personally I would have stored (another stored value) “speed” from the first SV rules as the speed-leader Stored value.
What you have should work just as well.

Thanks Dabbla !
And thanks for your patience
The whole automation thing is very confusing and complicated to me.

Nah. It doesnt work. Just checked.
I included my custom box setts as well.

In the custom column settings, change stored value to (market) not (selection).

I was going to test your file, I then realized I have this exact rule in my TPD file already.
I didn’t make it as I said above, I have made it the same as you,

[ilovepizza82]

Yes, it works now perfectly. Thank you !
