[HELP] About Tank Parts in DayZ!

[28WL]

Hi, I was working on the DayZ script, but I can't find where is the problems that I can't add Tank Parts to any vehicles, which has like 0/1 Tank Parts. When I want to add this item to the vehicle, I get the messages like: "You can't drop this!". So, if you are a good person, who could try to fix it or share it to me or help, do it. When vehicle has 1/1 Tank Parts - I can add to the vehicle's inventory Tank Parts how much I want like to storage it normally, but how I said, 0/1 --- I can't add, I get the message. I can give a free VIP at my server for your help as a gift for the help.

I fixed it by myself in 3 days. How can I say, it was worth it!
