When I use a create and remove trigger and presurve it.
And when I test my map the screen is just black. I push tab but still nothing.
Any suggestions?
Could you please fix that? I can't understand anything about it.
If your remove action directly follows the create action you will not see your unit and I don't think you will get any vision from it.
well i also tried puttin a wait time on it with out using hyper triggers but the problem is my mini map and my main screen is blank/black/nothing their.
ya no vision sorry couldn't think correctly. But wheni take presurve off the map reappears.

by the way the remove trigger are you sure you are no using for all units because you can be removing map revealers or something like that and gets you no vision
no just removin zerg egg and creating zerg egg also tried it with other units such as mariens and what not
its layed out as the following
switch 1 is set
create exactly 1 unit at location
remove exactly 1 unit at location
Pressurve trigger
Do this cuinhell.
1) Get switch 1 set for your trigger to work
2) Create exactly one unit for YOUR PLAYER at location
b. Wait 2000 seconds
c. Remove exactly one unit for YOUR PLAYER at location
d. Preserve Trigger
It's Preserve, not pressurve 
2000 seconds thats alot do you mean millseconds?
Yes, he means milliseconds.
I believe he does
Edit: Oops, biskit posted same time
You cannot create an egg with triggers.
Wow lost of people missed that...
ADDITION:
Just noticed said tried with other units?
ya i tried with other units also tried a trigger to kill you when it is created. But it kills you but no vision of the creation. But every other time I test it. It has no vision hmm wonder why?
No X-tra units can be created with triggers. The only way is that you can move the preplaced units to the apropriate location when needed.
