Created the following macro for sending a report and serial number.

<his:callsign> <his:sent_rpt> <his:sent_exch> <his:callsign> TU GL<stop>

I've got [xxx] in the sent exchange field in HRD Log. And it increments up each time I manually add a log entry.

When I hover the mouse over this macro button to see what the macro would send, it looks good, except <his:sent_exch> is shown in bold and struckthrough.
When I send that macro, all is good except that "his:sent_exch" is sent instead of the [xxx] number.

Am I overlooking something or leaving something out, that the <his:sent_exch> command is not picking up the number from the logbook?
