Syntax error after changing scripting language

[Yousef]

Hello guys, I changed the scripting language of a map I'm editing from jass to lua but now when I try to save it shows this error.

I don't think it's actually the scripting language that is causing that error but any help is appreciated.

Do you use vJass? I heard that and Lua are not cross-compatible yet, so pick one or the other unless I'm mistaken.
