[SOLVED] MvM Population File Errors

[Aoi]

Hi.
I've been trying to make my first pop file, and I've run into a few errors. It's for mvm_decoy.
When I try to play it no robots spawn, other than the few support sniper bots I've added, but sentry busters don't seem to be appearing. This is all that appears in the console:

Invalid populator 'WaveSpawn'
Parse Failed in CPopulationManager::Initialize for scripts/population/mvm_decoy_exhaustion.pop

I've attached the .pop file below. Thank you in advance.

Edit: I found what was wrong. I had closed the first Wave tag.

Wave
{
    StartWaveOutput
    {
        Target wave_start_relay
        Action Trigger
    }
    DoneOutput
    {
        Target wave_finished_relay
        Action trigger
    }
}

WaveSpawn
{
    //etc...
}

Instead of

Wave
{
    StartWaveOutput
    {
        Target wave_start_relay
        Action Trigger
    }
    DoneOutput
    {
        Target wave_finished_relay
        Action trigger
    }

   WaveSpawn
   {
       //etc...
   }
}
