L4D2: Tank Spawn?

Hi,

The progress of my map for Muhnay's Mapping Contest is around 95%.

There are only some issues left, including the fact that I don't know how to make the tank spawn at a certain point only. So, if someone knows this, can you please help me with it?

Sorry for a double post, but I do this because I have a new question so I want to bump this thread up again

I fixed the tank spawn, finally. But now, I'm having a different issue.

When I start the map, the only weapons that spawn are the primary weapons like the ak47.

All of the other items, including gas cans aren't there, while they ARE visible in the hammer editor.

Anyone has any experience with this?

Edit: If you want to know how I made a tank spawn, just PM me and I'll help you.
