How to fix my condition?

execute as @s[scores={kills=..0}]
If the player hasn't made a single kill yet? My actionbar display depends on it
Full line:
execute if score $activegame BCTF_setup matches 1 unless entity @e[type=minecraft:armor_stand,tag=DroppedRedFlag] as @s[scores={kills=.... 0},team=Red] run title @s actionbar ["",{"text": "Red team ", "color": "red"},{"score":{"name": "Red", "objective": "caps"}, "color": "#FD8181"},{"text":" ⚐", "color": "red"},{"text":" ", "color": "gray"},{"score":{"name":"Blue","objective":"caps"},"color":"#9494FF"},{"text":" ⚐","color":"blue"}," ",{"text":" Horn: ","color":"gray"},{"text":"\u25c7 \u25c7","color":"#fcba03"}]
