Hello OF Team,

I have a "trees" table nested within "plot". Using a hierarchical code list, I populate a value for the number of trees that exist at a plot (plot/n_trees with parent code plot/plot_id). I would like to use this value to define a function for the "Min Count" field in the "trees" table. I have tried simply "plot/n_trees" without success. How does one reference a code value and use it as an integer at a different node in the survey?

Thank you!

Dear Bryant,
If n_trees contains a number and it's defined as a numeric attribute, marked as calculated, it should be sufficient to use the attribute name in the expression, or try to use the function number(n_trees) to cast the value into a number.
Many thanks,
Open Foris Team
