[ngtrang]

I am trying to solve the unit errors with such variables (I attached the model to this question).

Those are actually warnings that you have passed a variable to a lookup that has a unit.

Traditionally, lookups are supposed to have a dimensionless X axis.

The following help entry details what you can do.
