The REPORT command still supports the SUMMARY clause; you'll need to use similar code to trigger the report in SUMMARY mode. You can use a variable, object property or whatever as you like - the code to trigger the output works the same way.

(IOW, you may need to modify your code in the form or .PRG to collect the information about whether or not SUMMARY should be used, and invoke it as appropriate.)
