How do I set up super secret level in MAPINFO?

[asd1994]

I've been trying to add a super secret level in my mod that can be accessed from the secret level, but it keeps taking me back to the standered levels. I can't figure out why. 

Here's my code:

 

map E1M7 "The X Labs"
{
    next = "E1M8"
    secretnext = "E1M9"
    music = "17_DARK"
    sky1 = "SKY1"
}

map E1M8 "The Bunker"
{
    music = "18_CHILD"
    sky1 = "SKY1"
    cluster = 1
    nointermission
    next = endpic, "TCR_END1"
}

map E1M9 "Necro-Evil"
{
    next = "E1M8"
    secretnext = "E1M10"
    music = "19_BLUD7"
    sky1 = "SKY1"
}

map E1M10 "Caco Canyon"
{
    Next = "E1M8"
    Music = "110_GEEZ"
    Sky1 = "SKY1"
}

 

If anyone could help me figure out whats broken, it would be most appreciated. :)

This could happen if you haven't constructed the map in question yet, but it looks like it should work. I'm not seeing any errors in your text.

Omg... I forgot to put E1M10 in the pk3! xD Thanks for making me realize that!
