Set variable to null when Clearing Selection

[#1]

I have two variables (Dates) I use in Calendar objects in my application and I would like to make them null whenever the user hits the clear button.

Anybody could help me with that ??

Why don´t you create a button that does it by "Actions" ? Your user should use it instead the clear button.

Is that what "Clear Other Fields" "Clear All" and "Clear Field" are supposed to do?
