need help darkrp

[ERROR] A runtime error has occurred in "addons/darkrpmodification-master_gmchosting/lua/darkrp_customthings/jobs.lua" on line 30.
The best help I can give you is this:

A table is being indexed by something that does not exist (table index is nil).

Hints:
- The thing between square brackets does not exist (is nil).

The responsibility for the error above lies with (the authors of) one (or more) of these files:
1. addons/darkrpmodification-master_gmchosting/lua/darkrp_customthings/jobs.lua on line 30
2. gamemodes/darkrp/gamemode/libraries/fn.lua on line 84

[ERROR] A runtime error has occurred in "gamemodes/darkrp/gamemode/modules/base/sv_gamemode_functions.lua" on line 714.
The best help I can give you is this:

DarkRP was unable to introduce player "greygod" to the game. Expect further errors and shit generally being fucked!

Hints:
- This error most likely does not stand on its own, and previous serverside errors have a very good chance of telling you the cause.
- Note that errors from another addon could cause this. Specifically when they're thrown during 'PlayerInitialSpawn'.
- This error can also be caused by some other addon returning a value in 'PlayerInitialSpawn', though that is less likely.
- Errors in your DarkRP configuration (jobs, shipments, etc.) could also cause this. Earlier errors should tell you when this is the case.

If you don't know where is 30 line - Download Notepad++
(on the left side of opened in netepad++ file you have line numbers. It helps)

If you don't know where is jobs.lua

Garry's mod > Addons > darkrpmodification-master > lua > darkrp_customthink > jobs.lua
Just PPM and open with notepad++

Now you see where is problem. If you don't know how to fix it just send it here.

Have you something edit in this .lua file or added a Job to darkrp? Have the file all permissions they need?

Please send us the Code line !

Cut the whole job that you made on that line and see if it still persists.
