getting the number of the current marked card

[Klaus Major]

Hi friends,

has anybody a receipe on how to get the number of the current marked 
card
in a series of marked cards (obviously :-)?

I want to supply a bg field which tells the user the (relative) number 
of the current
marked cd like "1 of (the num of marked cds)" after marking some cards 
ind a stack with e.g. 100 cards...

Know what i mean? How can i get this (relative) number?
Something obvious i am overlooking?

Thanks in advance.


Best
