Hi,

Put the Current Selection Box Object.

if there is any field value selected, it shows.

I want to know when that field was cleared so that I set a variable to a value

try,

=GetSelectedCount(Field)

if it is zero, then there is no value selected.

Maybe you creates (for testings) a selection history like:

variable: vFieldSelectionHistory

= '$(vFieldSelectionHistory)' & chr(9) & date(now(), 'MM/DD/YYYY') & chr(10) & getfieldselections(YourField)
