Hi, Patick
Thanks a lot for your reply.
The trouble is how to make a parent section contains two sections which have different shape, I managed to put them side by side now. if two sections are side by side with the same shape, it is easy to achieve, just group them into one section box. But these two sections has different shape because the tables under them have different shapes, one is longer than the other, so I wish I could group these two in one section group with a big T shape. but I cant. they only go square, and rectangle.
It seems achievable, if Group1 signed, Group1 and Group2 become read-only. Do I need the coding?
Cheers
Linda
