Hi all, I was trying to understand how to use expression within component inputs such as http://en.wiki.mcneel.com/default.aspx/McNeel/ExplicitHistoryPluginExpressionLanguage.html
But I couldn't understand how I can define a variable to be used in the expression field. If I follow the easy example in the above link I get an obvious runtime error saying the variable is not defined. How in general an expression is used within a component ? I apologise for the odd question! Cheers Giulio
