Upgrade/Trigger help

[minus17]

I've been looking around and can't find anything to solve my dilemma, if it can be solved. What I've got setup is just a basic upgrade with no effects attached to it. What I would like to have happen is that when this upgrade is completed that a trigger would fire off and modify a variable of mine. I've seen the action where "A unit finishes an upgrade" but then I cannot find a corresponding condition to confirm that this upgrade is the one I want and not some various other upgrade.

Any help/ideas would be appreciated.

Try the condition "Tech-type Comparison", and set the "tech-type researched" to whatever the upgrade is.
