Hallo Klaus.
Not really... what I want to be able to do is something like:
if this card is the first card of this stack then...
I've been trying all kinds of combinations in the msg box, but none of them works (errors like "chunk source is not a container, etc.)
Regards.

Bonjour Michel,
LC is all about PROPERTIES and to get and set them and cards have a NUMBER property, so:
Code: Select all
...
if the num of this cd = 1 then
## current card is the FIRST card in your stack, do your thing...
end if
...

Ah... the properties!
Thank you for pointing me in that direction!
And I see that I won't have to ask my followup question: how can I tell if I'm on the LAST card:
the number of the last cd of this stack
Danke, danke!

Avec plaisir, mon ami!
