Error:

client.lua:20: attempt to concatenate local v_1 (a nil value) 

wtf?

[EstrategiaGTA]

v1 is a nil value

[Turbe$Z]

what is the solution for this?

[_DrXenon]

you gotta define v_1 or v1. this script is missing lines tgat define those values.

They r not defined serverside nor client side.

[1B0Y]

v1 and v2 are returning nil. I'm guessing that you're calling this from the server, which in this case, you need to send the data in the trigger for v1 and v2.
