Having trouble with the following code how can I fix it?
**My Summon Enchant **
    "supported_items": "minecraft:iron_axe",

            },

            }
        }]
    }
}

MY RUN Wither Skeleton Summon command
execute unless score @s countdown matches 0 run tellraw @s {"text":"You Just Used This!","color":"red"}

# If the summoner's score is 0, run the summoning function
execute if score @s countdown matches 0 run function enchantments:summon_wither_skeleton```

My Summon Command
```# Tag the player to identify the summoner
tag @s add summoner

# Create the team if it doesn't exist
team add my_team

# Join the player to the team
team join my_team @s

# Summon a wither skeleton 1 block below the player and tag it
summon minecraft:wither_skeleton ~ ~1 ~ {Tags:["attacker"]}

# Play particle effect and sound effect simultaneously at the summoned skeleton's location
execute at @e[type=minecraft:wither_skeleton,tag=attacker] run particle minecraft:poof ~ ~1 ~ 0.5 0.5 0.5 0.1 100 force
execute at @e[type=minecraft:wither_skeleton,tag=attacker] run playsound minecraft:block.amethyst_block.chime master @a ~ ~1 ~ 0.5 1

# Add the summoned wither skeleton to the player's team
execute as @e[type=minecraft:wither_skeleton,tag=attacker] at @s run team join my_team @s

# Schedule the function to remove the wither skeleton after 5 seconds
schedule function entity_status:remove_wither_skeleton 5s

# Set the countdown score to 100 (5 seconds cooldown)
scoreboard players set @s countdown 100

# Schedule the tick function to decrement the countdown score
schedule function cooldowns:tick 1s

# Remove the summoner tag
tag @s remove summoner```

and finally my 

tick.mcfuncion 
Decrease the countdown score for players with a countdown score greater than 0
execute as @a[scores={countdown=1..}] run scoreboard players remove @s countdown 1

and tick.json

{
    "values": ["cooldowns:tick"]
  }```
