[Help] attemp to concatenate a nil value

Hello. I’m working on synchronization for my gang turf wars script and I have a serious problem. I wanted to make blips so every player from the attacking gang and defending gang can see the blips of enemy and friend npcs. This is working so far, but when it comes to syncing when they are dead… here is where the problem starts. Blips are still visible even after npc death. The print("ADDING ATTACKER BLIP WITH: " … pedID) doesn’t even show up in the console and I suppose that blips don’t even add to the table :confused:

EDIT1: Okay, adding blips to the list works good now. I just put pedID instead of pedId :unamused:

Yeah I think I have found the problem. It’s working now… probably. Still need to wait for my friend to test it out. Btw I didn’t knew that arrays start at 1 :scream:

Sorry lol, I thought the problem was solved :laughing:

Is the issue still the nil value, or are you getting a new error now?

It’s working properly now, no errors or anything and blips are successfully disseapring when certain NPC is dead but I can’t say for sure because I don’t have anyone to test it with right now. Btw to be honest this picture made me smile :laughing:
