Copying groups

[jbv at souslelogo.com]

Hi list,

I have a single card stack containing several groups,
each group containing several fields and images.
I need to copy these groups to a substack.
I use :
copy grp tname of cd 1 of this stack to cd 1 of stack myTarget

The weird thing is that all groups are copied, but the text
content of every field is missing.
What did I miss ?

Thank you in advance.
