how can i make result about 'cap_firm', 'commodity_use'?

[kor-GEMS]

※ I could't write english well. so thanks for your reading!

hi, i'm working in korea and my main role is forecating GHG emissions.

so we'd made a intergrating messageix model(power, industry, trs, bud..).

and we draw result 'OBJ', 'CAP', 'CAP_NEW' and so on.

my problem is, i want to draw 'CAP_FIRM', 'COMMIDITY_USE'.

but the python was like
'unhandled Java exception: There is no variable 'CAP_FIRM'!'

my code is ----------------------------------------------------------------------
table_CAP = scenrio.var('CAP') #-> no error
table_CAP_FIRM = scenrio.var('CAP_FIRM') #-> error

I'd confimed there is 'CAP_FIRM', 'COMMDITY_USE' in the GAMS, named 'MsgOut_MESSAGEix.gdx'.

and even it is var. not par, set.

so.. i want to help.. please help me!

thank you!
