I've volunteered to do a free laser and light show for some kids and I really need your help!

I'm using LSC Clarity PC and BEYOND to run the lasers and lights and for some reason the cue channel isn't working properly so I can select lasers cues in BEYOND from my DMX console. I was hoping to use the pango script in BEYOND to edit/fix the cue mapping so I can record the laser cells as lighting cues in my DMX console and synchronise with the lights. For example, my BEYOND DMX cue channel is 499, and I would like value 1-3 to select/run the first cue/cell in BEYOND, 4-6 the second cue/cell, and so on up to 256. Does anyone understand what I mean?
Can someone please teach or give me an example on how to write DMX cue mapping in BEYOND?
I would appreciate it a lot!

best regards,
Peter
