Hi @boubcher, since the ExpressionEvaluator evaluates the expression for each feature, all the attributes which are used in the expression have to be contained by a single feature. In this case, every "Brida" feature should have the "factor" attribute.
Consider merging the "factor" to the "Brida" features before inputting to the transformer. The FeatureMerger or the Joiner would help you to do that.
