Trouble setting units as variables

I'm trying to make a trigger where in the event that a specific unit dies, so and so happens. Right now im stuck on the event part.

Event Type: Unit - Specific Unit Event

In the box below it says

Unit and Dies

When I click on the Unit it looks like it needs me to select a specific unit, which is good because I want to make this work only when a specific unit dies. The problem is I can't find a way to select a specific unit.

(There is a button that says "Select a Unit" but when I press it, it opens up the Unit Tool Palette, and when I click the unit I want, nothing happens.)

Anyway, if you know what I should do to select a specific unit, please let me know

Thanks

Well, the select unit button is to select a unit inside the map terrain screen, not in the palette. It will select only that unit though. If you want a specific type of unit perhaps you should use a Generic unit event, and put a condition of type to it. Or you can in the start of the game create a event in a certain trigger for each unit of that type, and also for all that enter the game.

OHHH i see now, Thanks a lot!
