Adding a GR meter to JS Major Tom

[Darkhorse]

Hello everyone!
I would like to add a gain reduction meter to the included Major Tom JS plugin. I tried copying and pasting all the "@gfx" part and variables from the 1975 compressor to no avail. Having very little experience with coding, what steps must I follow to achieve this?

FWIW after pasting the gfx section from 1975, a recompiling error screen showed up reading: "@sample:166: syntax error: '@gfx 0 32 // description etc...' though I copied and pasted the exact same thing.

Thanks!
