indexed-repeat to pull individual layer elevation data, to view in 3D scenes

[NKneisel]

Hi, 

I'm a practicum student looking at ways to visualize snow, soils, geology, water data using elevations.

Using the repeat function for my layer data, and need to "pull data" from each elev_layer field from my 'snowlayers' repeat into my main form to visualize on my 3D by layer.  Also, I'd want to use the phot per-layer, but that's after I get this step done.

Anyway, I can use Sum(), Count(), Max-Min, Once etc. 

But indexed-repeat(${elev_layer}, ${snowlayers}, 1) only gives me a -1, -2 for each index 1, 2, for repeat I'm trying to access elev_layer integer data from.

Tried in both the repeat and outside repeat to see if that gives a different value, but it's the same.

Is there a step I'm missing?

Hello i'm Cesar, and as @NKneisel I'm Geologist too, i i have similar problem, but i'm trying to pull the data from a repeat to another but i'd just not work, apparently the index-repeat just pull the last data in the repeat group, i use "once()" function but just pull the first a second register from the repeat.
