Cant use any variable (not even global ones)

[Slastraf]

...
if Map:Load(mapfile)==false then return end

zombiesleft= 0
zombieskilled = 0
roundssurvived = 0
zombiesextrahealth = 0
...

this is in the main.lua script

function Script:NewRound()
roundssurvived= roundssurvived +1
local a = (roundssurvived*.1) + roundssurvived
self.maxEnemies= self.maxEnemies + Math:Round(a)
end

this is in an script attached to a pivot in the scene.

The title is misleading in parts, i havent tried local variables yet but it would be nosense.

 

"...: 41 : attempt to perform arithmetic on field 'currentround' (a nil value)"

I get this error, am very confused since the calculation below this line that I implemented today worked.

The script start() functions get called inside the Map::Load() function, so your variables have not bee declared yet at that time.
