Use an item from a list in a JMP column formula

[#1]

I seem to be able to pick out the first item in a list of columns and use that in a transpose function but the same approach does not work when used in a JMP column formula.  Divider doesn't evaluate as a column name in a formula but it does in a transpose function

Divider = yVars[1]

I suspect you are running into a scoping issue.  Is yVars in the same namespace as your column formula?.

Insert one expression into another using Eval Insert, Eval Expr, Parse, and Substitute
