[JASS] What does this mean when said in JassHelper?

[Vicboy]

Undeclared function IsValidLocationLoc
&
Cannot convert null to boolean

They both address the line:

                set udg_Temp_Boolean = IsValidLocationLoc(udg_Temp_SightLocation)

This line came from

Sight Cone System v4

I tried copy pasting the trigger folder of that map to my map but the variables didn't paste with it so I decided to manually add them. I don't want to exit my map and start over again because it's almost way past my bed time.

this means that the functon IsValidLocationLoc() isnt defined by the time the syntax checker reaches that line. The second error is a follow-up error; if you fix the first, you also fix the second.

Alright, thanks... Now, please, how can I fix it?

(I know it sounds like a lazy question, but I don't do jass)

You should obviously get the function called IsValidLocationLoc from wherever you copied this.

NEVER freaking open two threads for the same question.
