[JASS] Why this line has error?

[Lugia]

I am a beginner of making JASS script, so I always see other people script for learn. But when i use local Target = GetSpellTargetUnit(), a error occur when I save. It say need a handle or something. Why??? :?:

local type variable_name[b/] = value
Meaning you would need:
local unit target = GetSpellTargetUnit()

In other words, you missed the handle type.
