This is what i need please help!

[ZeroGaming]

so I need a conveyor belt script that teleports items 8 blocks in a straight line after spawned by this script my developer friend said he would help me but he didnt, it has been a long time since he said he would help me so please I need help with nbt, sorry if my english isnt good  information you may need:

the conveyor belt is needed to move items 5 blocks north, into a composter that despawns said item and gives your essentials balance 10$ 

the item is wheat seeds named &aGummy Bears and this is the script it is supposed to hook into (not really) its just the script that sets  it up also if you could, I want a script that on a specific pressure plate it deletes the pressure plate and 3 blocks in front of the pressure plate it does this: 

 

    set {dropper} to location of event-block
    set {up} to location 1 left {dropper}
    set {temp} to location 1 right event-block
    wait 1 second
    set block at location of {dropper} to top prismarine slab
    wait 1 second
    set block at location 1 left {dropper} to west facing prismarine stair 
    wait 1 second
    set block at location left {dropper} to {up}
    set block at location 1 left {dropper} to west facing prismarine stair 
    wait 1 second
    set block 1 above {up} to prismarine block
    wait 1 second
    set block 2 above {up} to west facing prismarine stair 
    wait 1 second
    set block 3 above {dropper} to bottom prismarine slab
    set block 2 above {dropper} to top prismarine slab
    wait 1 second
    set block 3 above {temp} to bottom prismarine slab
    wait 1 second
    set block 2 above {temp} to end rod
    wait 1 second
    while {dropper} is set:
        wait 80 ticks
        drop 1 wheat seeds named "&aGummy Bears" above location of {temp}
    if {dropper} is not set:
        stop
