Solved Fire Trail behind player?

[JustADev]

How do I fix my skript I made to make it so that when right clicking an item, whenever the player runs, a fire trail is behind the player, ie Flint and Steel Fire (Not Particles)

Code:

on rightclick with blaze powder:
    name of player's tool is "&eFire Dash &7(Right Click)":
        set {_loc} to location 2 meters behind player
        loop 10 times:
            spawn falling block of fire at {_loc}

on rightclick with blaze powder:
    name of player's tool is "&eFire Dash &7(Right Click)":
        loop 10 times:
            set block at block 1 blocks backwards player to fire
            wait 8 ticks

Now how do I make it despawn ?
