Crystal Reports Multi Select parameter - compare selected values with available values -


i have multi-select parameter ?foobar dynamically populated varying number of values.

is there way determine both total number of available values , number of values selected user?

so if list contained

a b c

and user selected

b c

i'd know there 3 available , 2 selected.

i know 2 selected because can interrogate ?foobar, not know how determine how many available in list (that is, without populating different parameter in report count.)
