i'm new in zombie mapping and I knew simple things but when I added the dog's spawner and start the game
he said script run time error
<see console for more details>
pair 'undefined' and 'zombie_door' has unmatching types
'undefined' and 'string'

I delete the dog's spawner then make it again and the same problem
please someone help me

this is what I write

"spawnflags" "3"
"script_forcespawn" "1"
"script_noteworthy" "zombie_dog_spawner"
"script_string" "zombie_chaser""targetname" "zombie_spawner_dog_init"
