Stranger things table and Full DMD. How do i make this work?

[gravitygroove]

Howdy, Attempting to get the table i got here:

to work on 3 screen setup, displaying videos on fulldmd, and regular BG. However, when i edit the script following the included instructions, it just gives the error on the far left image, "variable is undefined " one of the lines in instruction is gibberish (IF you are using a full dmd, uncomment here to enable the B2S backglass)  --what the hell is uncomment supposed to mean?

it works fine stock, the same as the original table, playfield and active BG work, but when i tinker with any of the parameters it says too, it just won't work. I'm new to this and trying to understand what im missing.

do you still need help with this.

 

uncomment means to erase it or change the number to what screen you want it on.

if that is what you are asking.

or if its a pup pack change it in the pup pack editor
