I am somewhat of a novice when it comes to programming parameter formulas and when doing so, I usually struggle with proper syntax and as you know if there's ANYTHING wrong in the formula structure it isn't going to work...and I was thinking it would be great if Revit would "suggest" possible proper structuring of a formula if the user doesn't have it quite right. It would work similar to how Google asks you if this is what you really want...when you spell a word wrong in your search bar.
I think this would save a lot of frustration for users who aren't experts at writing code, and still allow them to further customize their parameters.
Thanks.
