Trick or trade question

Botto_

Hi guys,
I'm new on CF NA and I saw this Trick and trade thing. I bought a key, opened the 'gift' and came out a green XF gun for 15 days.
I didn't know what to do, I tried to settle 1.000 ZP, then 10.000, the system was not allowing to do that even after agreed.
Then I pushed USE gun, but says NO VIP FOUND so I cannot even use it.

Can you explain me better this thing?

It's called Trade Box which you get while being active in game,item which you get its called VFX effect which can be put on vvip weapons like m4a1-obsidian beast,barret m82a1 obsidian beast which change visual appereance

In your case you could not use it bcs you didnt have vvip weapon
