Colorize inside loop

Hi all,

I'm really new to the Visual Scripting app, so it may be that there are some mechanism's that I don't understand yet. But I'm trying to colorize my model in different layers through the loop function, using the accumulator at the end to get the complete object list from the loop. As you can see from the attached movie clip, my colorizing is working fine when I debug using a manual integer, but when I connect the accumulator the colors are gone.

Is this functionality not supported yet, or is it simply a user error? Any help on this topic would be highly appreciated.

Thanks, Vegar.
