First of all, yes i did mount css and i did change the config.lua. My problem is that when i spawn the vault, an error is spamming the Console. Here it is:
[ERROR] addons/bank_robbery/lua/entities/bank_vault/cl_init.lua:32: attempt to index global 'BankConfig' (a nil value)
1. unknown - addons/bank_robbery/lua/entities/bank_vault/cl_init.lua:32

Yes, i do know a bit lua so i tried to fix it. I couldnot make out what the problem was. Please help an old man (me) getting his cup of tea.

Edit: BTW, the error makes the whole addon useless. So, no robbing..
