Respawn Timers in map not working?

I keep getting this error in console:

!! ERROR: bad input/output link:
!! tf_gamerules(koth_gamerules,SetRedTeamRespawnWaveTime) doesn't match type from <null>(<null>)
!! ERROR: bad input/output link:
!! tf_gamerules(koth_gamerules,SetBlueTeamRespawnWaveTime) doesn't match type from <null>(<null>)

Does anyone know what it means?

 

Your logic isnt set up correctly. If triggered from logic_relay, It should be something like:

OnTrigger <name of your tf_gamerules here> SetRedTeamRespawnWaveTime 4
