Help with item drop

[seaseasea]

Hi all, I'm doing Capture the Flag mode and at some point I need to reset the flag when a player dies.
And in one of the main code snippets I use the following code:

drop 1 red banner at {_deathGray}

But this piece of code doesn't work and gives an error "Can't understand this condition/effect: ...".
What should I specify instead of the red banner?
I've looked through the documentation, but I still don't understand how to do it. I'm just starting to write in Skript, so maybe I'm missing something.
Sorry for possible mistakes, I used translator (I'm from Russia).

it seems like skript doesn't know what is "red banner" but your code does work if you try only "banner" witch is kinda weird. if i will find i way ill let you know.

The strange thing is that, for example in this code:

if event-block is red_banner:

it determines the color of the banner. It's very strange.
