Hi! Little problem there. Can someone tell me what's the problem with this? The first test below works while the second doesn't. I have to use strict so I need to know why it doesn't work and what I have to do to fix the problem in the second test. It complains when I put items in the second dimension of the array..."Can't use string ("group 0") as an ARRAY ref while "strict refs" in use at test.pl line 18." Thx a lot! Franck
