Hey! Can't solve this for many hours now I pass ‘split_loc2’ into expression, and it yields ‘0’. If I change it to something like ‘P’, it will properly show coordinate tho. What am I missing? ‘split_loc2’ is attribute too, and it is clearly inside spreadsheet one step before the for-loop I am running.

Those look like string attributes. You can't use point() with string attributes. There are string versions of each of the attribute reference functions ending in ‘s’, ie “points()”

oh!! thank you!!
