css teams full??

I made a css map but whenever I try to test it it says both the Counter and the Terrorist teams are full when i am the only one in the game... Help??

You get that if you have either no info_player_counterrorist or
info_player_terrorist entites, or the ones you do have are invalid
(e.g. they're too close to or touching a brush).

If you've put them in, try raising them slightly, a few units above the ground.
