Currently Offset only applies to the range or group immediately before the offset command, so [Group 1 offset] or [chan 1 Thru 10 Offset].
This allows for [chan 1 + Group 10 Offset 3] where the offset 3 only applies to group 3, not to chan 1. The error you are seeing is because the offset command follows a single channel which cannot be offset.
We are changing this syntax though, so that offset applies to all channels that come before it in the command line, in which case your command line will work.
