Aurthur,
You can only have one command ( or stored procedure ) per crystal report.
so you then have a couple of options.
You could rewrite the command into a single command. ( How to do that is a different forum and I'm assuming that writing SQL code is beyond your current abilities ) or have whoever gave you the code do it.
....or you could make the plan summary command drive the main report and than build a subreport using the frame useage command and then you would need to add the subreport to the main report and link them based on a common field ( Like Plan number ??? - I don't have the time to dive deeply into the code someone gave you.
