Understanding what Offset is Modifying

The right syntax will be 1 THRU 10 Cell 15 Offset 2

Offset Odd is based on the channel number ( this is why you have an error, because 15 cannot be even...)

odd based on selection : OFFSET 2

even based on selection : OFFSET 2/2

I guess I'm still struggling with the idiosyncrasies of what "OFFSET" modifies with multi-cell fixtures. Sometimes it modifies Channels, sometimes it modifies Cells, and sometimes it modifies differently based on the combo of Channels + Cells. 

Here's where I think I'm at:

• The placement of “Offset” bares no change to the behavior of what is modified.

• Odd / Even pay no mind to Channel when Cell, or a group of Cells, are specified.

• Offset # only modifies Channel when a single Cell is specified, if more than one Cell is specified it modifies Cells instead.

• Offset 2 and Offset 2/2 modify Cells, and has contextual differences on even vs odd Channels.

• Offset 3 modifies Cells Only.

• Offset 4 modifies Cells, and has contextual differences on even vs odd Channels.

Examples:

Chan 1 Thru 10 Offset 2 Cell 15 

 - Modifies Channel, Channels 1, 3, 5, 7, 9 selected; only Cell 15 selected for each

Chan 1 Thru 10 Cell 15 Offset 2 

 - Same as previous 

Chan 1 Thru 10 Offset 2/2 Cell 15 

 - Modifies Channel, Channels 2, 4, 6, 8, 10 selected; only Cell 15 selected for each

Chan 1 Thru 10 Cell 15 Offset 2/2

 - Same as previous 

Chan 1 Thru 10 Offset Odd Cell 15

 - No Modification to Channel, Channels 1-10 selected; Cell 15 selected for each

Chan 1 Thru 10 Cell 15 Offset Odd

 - Same as previous 

Chan 1 Thru 10 Offset Even Cell 15

 - Nothing Selected, as it is modifying Cells and the Cell is Odd

Chan 1 Thru 10 Cell 15 Offset Even

 - Same as previous

Chan 1 Thru 10 Offset 2 Cell 1 Thru 15 

 - Modifies Cells, Channels 1-10 Selected; Odd Cells Selected on Odd Channels, Even Cells Selected on Even Channels 

Chan 1 Thru 10 Cell 1 Thru 15 Offset 2 

 - Same as previous

Chan 1 Thru 10 Offset Odd Cell 1 Thru 15

 - Modifies Cells, Channels 1-10 Selected; Odd Cells Selected on All Channels

Chan 1 Thru 10 Cell 1 Thru 15 Offset Odd 

 - Same as previous

Puh... there is quite some difficultys.
