Error.. :O

[iPot]

I'm making my own gamemode and while fixing much errors in the meanwhile i can't get past this 1..

What does it means ? Any help ?

[23:12:36] start: Failed to start resource 'Species wars' 
[23:12:36] ERROR: mapmanager: map resource could not be started. 
[23:12:36] ERROR: call: Check the function exists, is exported and you've passed 
 the correct arguments 
  

Thank you,

Tom
