Hi,
I have attempted to run a complex sampling procedure. However, SPSS has
always given me an error message "Subcommand  Size: A valid category list
must be specified for matrix." I understood the message and tried different
ways to manipulate the syntax. However, it was useless. I am stuck with the
error message now. I wonder if anyone could help me solve this issue. The
syntax is written below. Thanks so much!

ignore it).
